ade2bfe7d1 [BNX2]: Fix UDP checksum verification
Fix TCP/UDP checksum verification. Use status bits in the buffer
descriptor instead of the checksum value to verify rx checksum.
Using the checksum value will be incorrect if the UDP packet has
zero in the UDP checksum field.

Firmware update required for this fix.

b090ae2b59 [BNX2]: Improve handshake with firmware
Improve handshake with bootcode with the following changes:

1. Increase timeout to 100msec and use msleep instead of udelay.

2. Add more error checking for timeouts and errors.

e29054f92d [BNX2]: Fix VLAN on ASF
Always set up the device to strip incoming VLAN tags when ASF is
enabled. ASF firmware will not parse packets correctly if VLAN tags
are not stripped.

f4e418f7f3 [PATCH] bnx2: refine bnx2_poll
Refine bnx2_poll() logic to write back the most up-to-date status tag
when all work has been processed. This eliminates some occasional
extra interrupts when a older status tag is written even though all
work has been processed.

The idea is to read the status tag just before exiting bnx2_poll() and
then check again for any new work. If no new work is pending, the
status tag written back will not generate any extra interrupt. This
logic is similar to the changes David Miller did to tg3_poll().

e3648b3d8d [PATCH] bnx2: update firmware handshake for 5708
Dynamically determine the shared memory location where eeprom
parameters are stored instead of using a fixed location.

Add speed reporting to management firmware. This allows management
firmware to know the current speed without contending for MII
registers.

c921e4c4db [BNX2]: Fix bug in irq handler and add prefetch
Fix bug in bnx2_interrupt() that caused an unnecessary register read.
The BNX2_PCICFG_MISC_STATUS should only be read when the status tag
has not changed.

Add prefetch of the status block in bnx2_msi() similar to tg3_msi().
The status block is not touched in bnx2_msi() and prefetching it will
speed up bnx2_poll() that will run on the same CPU that received the
MSI.

Update version.

e89bbf1049 [BNX2]: remove atomics in tx
Remove atomic operations in the fast tx path. Expensive atomic
operations were used to keep track of the number of available tx
descriptors. The new code uses the difference between the consumer
and producer index to determine the number of free tx descriptors.

As suggested by Jeff Garzik, the name of the inline function is
changed to all lower case.

cd339a0ed6 [BNX2]: speedup serdes linkup
This speeds up link-up time on 5706 SerDes if the link partner does
not autoneg, a rather common scenario in blade servers. Some blade
servers use IPMI for keyboard input and it's important to minimize
link disruptions.

The speedup is achieved by shortening the timer to (HZ / 3) during
the transient period right after initiating a SerDes autoneg. If
autoneg does not complete, parallel detect can be done sooner. After
the transient period is over, the timer goes back to its normal HZ
interval.

As suggested by Jeff Garzik, the timer initialization is moved to
bnx2_init_board() from bnx2_open().

An eeprom bit is also added to allow default forced SerDes speed for
even faster link-up time.

afdc08b9f9 [BNX2]: Fix rtnl deadlock in bnx2_close
This fixes an rtnl deadlock problem when flush_scheduled_work() is
called from bnx2_close(). In rare cases, linkwatch_event() may be on
the workqueue from a previous close of a different device and it will
try to get the rtnl lock which is already held by dev_close().

The fix is to set a flag if we are in the reset task which is run
from the workqueue. bnx2_close() will loop until the flag is cleared.
As suggested by Jeff Garzik, the loop is changed to call msleep(1)
instead of yield() in the original patch.

flush_scheduled_work() is also moved to bnx2_remove_one() before the
netdev is freed.
