[PATCH] Add firmware version printout to wireless-2.6 (bcm43xx-softmac)

[PATCH] Add firmware version printout to wireless-2.6 (bcm43xx-softmac)

[Larry Finger]

John,

Please add this patch by Martin Langer to wireless-2.6.

Larry

==============================

This patch prints microcode revision, patchlevel, date and time to
KERN_INFO. Also, version 4.xx microcodes (rev>0x128) will be rejected
by the driver, because they still do not work.
