qlge: Fix a deadlock when the interface is going down

Currently qlge can deadlock when the interface is going
down, and the mpi_port_cfg_work() is executing on another
processor. It happens because unregister_netdev() holds
the rtnl lock, and the mpi_port_cfg_work() also request
this lock.

Since unregiter_netdev() may wait mpi_port_cfg_work(), who
also request the holding lock, it can cause an deadlock,
displaying the following error:

iwlwifi: do not spuriously call ieee80211_scan_completed

When a scan is aborted because the corresponding
virtual interface is removed, we may still later
attempt to tell mac80211 that the scan completed.
This is obviously wrong, since we already told it
that it was aborted, so don't do that.

is locked during the whole function so the local variables are safe.

p54: improve eeprom parser

Like other vendors, p54* devices have a checksum for

parser code to generate and verify the data fields,
before initializing the radio-chip on the card.

Note:
If you have to bootstrap an alternative EEPROM image
for your device and you don't know how to generate a
valid crc ccitt checksum, you should take a look at:
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git
