change indications. From Sergei Shtylyov.
23) Fix crashes during spurious ECI interrupts in sh_eth driver, also

Fix bug for DM9000 revision B which contain a DSP PHY
DM9000B use DSP PHY instead previouse DM9000 revisions' analog PHY,
So need extra change in initialization, For
explicity PHY Reset and PHY init parameter, and
first DM9000_NCR reset need NCR_MAC_LBK bit by dm9000_probe().
Following DM9000_NCR reset cause by dm9000_open() clear the
NCR_MAC_LBK bit.
Without this fix, Power-up FIFO pointers error happen around 2%
rate among Davicom's customers' boards. With this fix, All above
cases can be solved.

The 'link' field of 'struct sh_eth_private' has type 'enum phy_state' while the
'link' field of 'struct phy_device' is merely *int* (having values 0 and 1) and
the former field gets assigned from the latter. Make the field match, getting
rid of incorrectly used PHY_DOWN value in assignments/comparisons.

At least on Renesas R8A7778, EESR.ECI interrupt seems to fire regardless of its
mask in EESIPR register. I can 100% reproduce it with the following scenario:
target is booted with 'ip=on' option, and so IP-Config opens SoC Ether device
but doesn't get a proper reply and then succeeds with on-board SMC chip; then
I login and try to bring up the SoC Ether device with 'ifconfig', and I get
an ECI interrupt once request_irq() is called by sh_eth_open() (while interrupt
mask in EESIPR register is all 0), if that interrupt is accompanied by a pending
EESR.FRC (frame receive completion) interrupt, I get kernel oops in sh_eth_rx()
because sh_eth_ring_init() hasn't been called yet!
The solution I worked out is the following: in sh_eth_interrupt(), mask the
interrupt status from EESR register with the interrupt mask from EESIPR register
in order not to handle the disabled interrupts -- but forcing EESIPR.M_ECI bit
in this mask set because we always need to fully handle EESR.ECI interrupt in
sh_eth_error() in order to quench it (as it doesn't get cleared by just writing
1 to the this bit as all the other interrupts).
While at it, remove unneeded initializer for 'intr_status' variable and give it
*unsigned long* type, matching the type of sh_eth_read()'s result; fix comment.

The code handling the absent LINK signal (or the absent PSR register -- which
reflects the state of this signal) is quite naive and has probably never really
worked. It's probably enough to say that this code is executed only on the LINK
change interrupt (sic!) but even if we actually have the signal and choose to
ignore it (it might be connected to PHY's link/activity LED output as on the
Renesas BOCK-W board), sh_eth_adjust_link() on which this code relies to update
'mdp->link' gets executed later than the LINK change interrupt where it is
checked, and so RX/TX never get enabled via ECMR register.
So, ignore the LINK changed interrupt iff LINK signal is absent (or just chosen
not to be used) or PSR register is absent, and enable/disable RX/TX directly in
sh_eth_adjust_link() in this case.

WOL is broken because the magic packet status bit is getting set rather
than the enable bit. The PMT interrupt is not getting serviced because
the PMT interrupt is also enabled on the global interrupt, but not
cleared by the global interrupt and the global interrupt is higher
priority. This fixes both of these issues to get WOL working.
There's still a problem with receive after resume, but at least now we
can wake-up.

If skb allocation for the rx ring fails repeatedly, we can reach a point
were the ring is empty. In this condition, the driver is out of sync with
the h/w. While this has always been possible, the removal of the skb
recycling seems to have made triggering this problem easier.

This patch enables RX of jumbo frames for LAN7500.
Previously the driver would transmit jumbo frames succesfully but
would drop received jumbo frames (incrementing the interface errors
count).
With this patch applied the device can succesfully receive jumbo
frames up to MTU 9000 (9014 bytes on the wire including ethernet
header).

Currently if either arp_interval or miimon is disabled, they both get
disabled, and upon disabling they get executed once more which is not
the proper behaviour. Also when doing a no-op and disabling an already
disabled one, the other again gets disabled.
Also fix the error messages with the proper valid ranges, and a small
typo fix in the up delay error message (outputting "down delay", instead
of "up delay").

The sky2 driver doesn't count the Receive Overflows because the MAC
interrupt for this event is not set in the MAC's interrupt mask.
The MAC's interrupt mask is set only for Transmit FIFO Underruns.
Fix: The correct setting should be (GM_IS_TX_FF_UR | GM_IS_RX_FF_OR)
Otherwise the Receive Overflow event will not generate any interrupt.
The Receive Overflow interrupt is handled correctly

When calculating "offset" for final RSSI calibration we're using numbers
bigger than s8 can hold. We have for example:
offset[j] = 232 - poll_results[j];
formula. If poll_results[j] is small enough (it usually is) we treat
number's bit as a sign bit. For example 232 - 1 becomes:
0xE8 - 0x1 = 0xE7, which is not 231 but -25.
This code was introduced in e0c9a0219a8f542e3946fe972a68aacf8c3f906c
and caused stability regression on some cards, for ex. BCM4322.

Intermittently, b43 will report "Out of order TX status report on DMA ring".
When this happens, the driver must be reset before communication can resume.
The cause of the problem is believed to be an error in the closed-source
firmware; however, all versions of the firmware are affected.
This change uses the observation that the expected status is always 2 less
than the observed value, and supplies a fake status report to skip one
header/data pair.
Not all devices suffer from this problem, but it can occur several times
per second under heavy load. As each occurence kills the unmodified driver,
this patch makes if possible for the affected devices to function. The patch
logs only the first instance of the reset operation to prevent spamming
the logs.

We're using "mind" variable to find the VCM that got the best polling
results. For each VCM we calculte "currd" which is compared to the
"mind". For PHY rev3+ "currd" gets values around 14k-40k. Looking for a
value smaller than 40 makes no sense, so increase the initial value.

There is a race between the restart flow and the workers.
The workers are cancelled after the fw is already killed
and might send HCMD when there is fw to handle them.
Simply check that there is a fw to which the HCMD can be
sent before actually sending it.

This patch is a bug fix for an issue wherein power save was not
working for PCIe. This happens because for processing power save
sleep confirm command we pull skb so that skb->data points ahead
of interface header. We use same skb to get other cmda responses
as well. So if we don't push skb after processing cmd response,
it results into reduction in skb->len and finally skb->len reaches
zero. This causes failure in processing sleep command response.
Fix this by pushing skb by INTF_HEADER_LEN at the end of command
response processing.

Some network drivers use a non default hard_header_len
Transmitted skb should take into account dev->hard_header_len, or risk
crashes or expensive reallocations.
In the case of aoe, lets reserve MAX_HEADER bytes.
David reported a crash in defxx driver, solved by this patch.

====================
here's a patch series for net for the v3.9 release cycle. Fengguang Wu found
two problems with the sja1000 drivers:
A macro in the SH architecture collides with one in the sja1000 driver. I
created a minimal patch suited for stable, only changing this particular
define. (Once net is merged back to net-next, I'll post a patch to uniformly
use a SJA1000_ prefix for the sja100 private defines.) If you prefer, I can
squash both patches together.
Fengguang further noticed that the peak pcmcia driver will not compile on archs
without ioport support. I created a patch to limit the driver to archs which
select HAS_IOPORT in Kconfig.

arch/sh/include/asm/ptrace_32.h:25:0: note:
this is the location of the previous definition
A SJA1000_ prefix is added to the offending sja1000 define only, to make a
minimal patch suited for stable. A later patch will add a SJA1000_ prefix to
all defines in sja1000.h.

Commit 184b89044fb6e2a74611dafa69b1dce0d98612c6 ("tg3: Use VPD fw version
when present") introduced VPD parsing that contained a potential length
overflow.
Limit the hardware's reported firmware string length (max 255 bytes) to
stay inside the driver's firmware string length (32 bytes). On overflow,
truncate the formatted firmware string instead of potentially overwriting
portions of the tg3 struct.

As reported by Wu Fengguang's build robot tracking sparse warnings, the
dma_spec arguments in the dw_dma_xlate are already byte swapped on
little-endian platforms and must not get swapped again. This code is
currently not used anywhere, but will be used in Linux 3.10 when the
ARM SPEAr platform starts using the generic DMA DT binding.

Since commit a1fd287780c8e91fed4957b30c757b0c93021162:
"[media] bttv-driver: fix two warnings"
cropcap.defrect.height and cropcap.bounds.height for the PAL entry are 32
resp 30 pixels too large, if a userspace app (ie xawtv) actually tries to use
the full advertised height, the resulting image is broken in ways only a
screenshot can describe.
The cause of this is the fix for this warning:
drivers/media/pci/bt8xx/bttv-driver.c:308:3: warning: initialized field overwritten [-Woverride-init]
In this chunk of the commit:
@@ -301,11 +301,10 @@ const struct bttv_tvnorm bttv_tvnorms[] = {
/* totalwidth */ 1135,
/* sqwidth */ 944,
/* vdelay */ 0x20,
- /* sheight */ 576,
- /* videostart0 */ 23)
/* bt878 (and bt848?) can capture another
line below active video. */
- .cropcap.bounds.height = (576 + 2) + 0x20 - 2,
+ /* sheight */ (576 + 2) + 0x20 - 2,
+ /* videostart0 */ 23)
},{
.v4l2_id = V4L2_STD_NTSC_M | V4L2_STD_NTSC_M_KR,
.name = "NTSC",
Which replaces the overriding of cropcap.bounds.height initialization outside
of the CROPCAP macro (which also initializes it), with passing a
different sheight value to the CROPCAP macro.
There are 2 problems with this warning fix:
1) The sheight value is used twice in the CROPCAP macro, and the old code
only changed one resulting value.
2) The old code increased the .cropcap.bounds.height value (and did not
touch the .cropcap.defrect.height value at all) by 2, where as the fixed
code increases it by 32, as the fixed code passes (576 + 2) + 0x20 - 2
to the CROPCAP macro, but the + 0x20 - 2 is already done by the macro so
now is done twice for .cropcap.bounds.height, and also is applied to
.cropcap.defrect.height where it should not be applied at all.
This patch fixes this by adding an extraheight parameter to the CROPCAP entry
and using it for the PAL entry.

fimc_m2m_job_finish() has to be called with the m2m context for the necessary
cleanup while resume. But currently fimc_m2m_job_finish() always passes m2m
context as NULL.
This patch preserves the context before making it null, for necessary cleanup.

gsc_m2m_job_finish() has to be called with the m2m context for the necessary
cleanup while resume. But currently gsc_m2m_job_finish() always passes m2m
context as NULL.
This patch preserves the context before making it null, for necessary cleanup.
Use gsc_m2m_opened() instead gsc_m2m_active() in gsc_resume().
