6901031372 bnx2: Fix problem of using wrong IRQ handler.
The MSI-X handler was chosen before the call to pci_enable_msix().
If MSI-X was not available, the wrong MSI-X handler would be used in
INTA mode.  This would cause a screaming interrupt problem because
INTA would not be cleared by the MSI-X handler.

Fixed by assigning MSI-X handler after pci_enable_msix() returns
successfully.  Also update version to 1.9.3.

Thomas Chenault <thomas_chenault@dell.com> helped us find this problem.

990ec3804b bnx2: Fix jumbo frames error handling.
If errors are reported on a frame descriptor, we need to
account for the buffer pages that may have been used for this
error packet and recycle them.  Otherwise, we may get the wrong
pages for the next packet.

288379f050 net: Remove redundant NAPI functions
Following the removal of the unused struct net_device * parameter from
the NAPI functions named *netif_rx_* in commit 908a7a1, they are
exactly equivalent to the corresponding *napi_* functions and are
therefore redundant.

908a7a16b8 net: Remove unused netdev arg from some NAPI interfaces.
When the napi api was changed to separate its 1:1 binding to the net_device
struct, the netif_rx_[prep|schedule|complete] api failed to remove the now
vestigual net_device structure parameter.  This patch cleans up that api by
properly removing it..

efba01803c bnx2: Add workaround to handle missed MSI.
The bnx2 chips do not support per MSI vector masking.  On 5706/5708, new MSI
address/data are stored only when the MSI enable bit is toggled.  As a result,
SMP affinity no longer works in the latest kernel.  A more serious problem is
that the driver will no longer receive interrupts when the MSI receiving CPU
goes offline.

The workaround in this patch only addresses the problem of CPU going offline.
When that happens, the driver's timer function will detect that it is making
no forward progress on pending interrupt events and will recover from it.

Eric Dumazet reported the problem.

We also found that if an interrupt is internally asserted while MSI and INTA
are disabled, the chip will end up in the same state after MSI is re-enabled.
The same workaround is needed for this problem.

babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

pci_dma_mapping_error().

f22828e89f bnx2: Reinsert VLAN tag when necessary.
In certain cases when ASF or other management firmware is running, the
chip may be configured to always strip out the VLAN tag even when
