[patch 01/26] BNX2: Fix netdev watchdog on 5708.

[Greg KH]

-stable review patch.  If anyone has any objections, please let us know.

------------------

There's a bug in the driver that only initializes half of the context
memory on the 5708.  Surprisingly, this works most of the time except
for some occasional netdev watchdogs when sending a lot of 64-byte
packets.  This fix is to add the missing code to initialize the 2nd
half of the context memory.

Update version to 1.5.8.2.
