net: systemport: Track per TX ring statistics
bcm_sysport_tx_reclaim_one() is currently summing TX bytes/packets in a
way that is not SMP friendly, mutliples CPUs could run
bcm_sysport_tx_reclaim_one() independently and still update
stats->tx_bytes and stats->tx_packets, cloberring the other CPUs
statistics.
Fix this by tracking per TX rings the number of bytes, packets,
dropped and errors statistics, and provide a bcm_sysport_get_nstats()
function which aggregates everything and returns a consistent output.
