Change Details:
- Made IOC auto_recovery synchronized and not timer based.
- Only one PCI function will attempt to recover and reinitialize
the ASIC on a failure, that too after all the active PCI
functions acknowledge the IOC failure.

Change Details:
- Check HW ready condition before accessing h/w register in data-path
- Postpone clean-up of data buffers to the data-path restart path and
wait in the cleanup routines for in-flight DMA to complete
- Separate out Tx completion processing from Rx poll routine

Many (but not all) drivers check to see whether there is a vlan
group configured before using a tag stored in the skb. There's
not much point in this check since it just throws away data that
should only be present in the expected circumstances. However,
it will soon be legal and expected to get a vlan tag when no
vlan group is configured, so remove this check from all drivers
to avoid dropping the tags.

As suggested by Stephen Hemminger:
1) Made functions and data structures static wherever possible.
2) Removed unused code.

This fix handles the case when IRQ handler is called (for shared IRQs)
even before the driver is ready to handle interrupts.

fresh skbs have ip_summed set to CHECKSUM_NONE (0)
We can avoid setting again skb->ip_summed to CHECKSUM_NONE in drivers.
Introduce skb_checksum_none_assert() helper so that we keep this
assertion documented in driver sources.
Change most occurrences of :
skb->ip_summed = CHECKSUM_NONE;
by :
skb_checksum_none_assert(skb);

get_stats() method incorrectly clears a global array before folding
various stats. This can break SNMP applications.
Switch to 64 bit flavor to work on a user supplied buffer, and provide
64bit counters even on 32bit arches.
Fix a bug in bnad_netdev_hwstats_fill(), for rx_fifo_errors, missing a
folding (only the last counter was taken into account)

This is the patch to fix the build break caused by multiple
definitions of symbols between Brocade's FC/FCOE driver(BFA)
and 10G Networking Driver(BNA).
Changes are:
1. locally used functions are made static
2. unused functions are removed
3. using unique namespaces for the function names that must be
globally visible
