BZ 516833 [2/2] netxen - P3+ updates
These patches bring the RHEL 5 driver up to parity with the upstream
driver. The upstream commits are listed below. This second patch
includes changes from to 2.6.31 to 2.6.32.
This work has been tested at QLogic. It applies and builds cleanly with
2.6.165.

netxen: fix tx timeout recovery
Redesign tx timeout handling in line with new firmware
reset design that co-ordinates with other PCI function
drivers.
o For NX3031, first try to reset PCI function's own
context before requesting firmware reset.
o For NX2031, since firmware heartbit is not supported
directly request firmware reset.

netxen: firmware hang detection
Implement state machine to detect firmware hung state
and recover. Since firmware will be shared by all PCI
functions that have different class drivers (NIC or
FCOE or iSCSI), explicit hardware based serialization
is required for initializing firmware.
o Used global scratchpad register to maintain device
reference count. Every probed pci function adds to
ref count.
o Implement timer (delayed work) for each pci func
that checks firmware heartbit every 5 sec and detaches
itself if firmware is dead. Last detaching function
reloads firmware. Other functions wait for firmware
init, and re-attach themselves.
Heartbit is not supported by NX2031 firmware.
