Bug fix: Protect statistics ramrod sending code and a statistics counter update

a statistics ramrods with the same sequence number or with sequence numbers not

This patch introduces the parity errors handling code for 57710 and 57711 chips.
HW is configured to stop all DMA transactions to the host and sending packets to the network
once parity error is detected, which is meant to prevent silent data corruption.
At the same time HW generates the attention interrupt to every function of the device where parity
has been detected so that driver can start the recovery flow.
The recovery is actually resetting the chip and restarting the driver on all active functions
of the chip where the parity error has been reported.

Access to fp->tx_bd_prod is protected by __netif_tx_lock, so we do not
need any barrier for that.
Update of fp->tx_bd_cons in bnx2x_tx_int() is not protected by lock, but
barrier() nor smb_mb() in bnx2x_tx_avail() not guarantee we will see
values that is written on other cpu. Ordering issues between
netif_tx_stop_queue(), netif_tx_queue_stopped(), fp->tx_bd_cons = bd_cons
and bnx2x_tx_avail() are already handled by smp_mb() in bnx2x_tx_int()
and bnx2x_start_xmit().

[Resending with the proper subject. Sorry for the mess. ]
This patch is based on the RFC of Stanislaw Gruszka.
More specifically it fixes two possible races:
- One, described by Stanislaw, may lead to permanent disabling of the Tx
queue.
This is fixed by adding the smp_wmb() to propagate the BD consumer
change towards the memory.
- Second may lead to bnx2x_start_xmit() returning NETDEV_TX_BUSY.
This is fixed by taking a tx_lock() before rechecking the number of
available Tx BDs.
