The output of show_version() is confusing at best, and can also be
considered wrong if you don't know that the order of the API and
SERIAL number has been switched. The unusual dotted hex is also
unecessary unreadable and different from the filename convention and
outout from iwl_read_ucode():
bjorn@nemi:~$ cat /sys/class/net/wlan0/device/version
fw version: 0x8.0x18.0xC.0x2
fw type: 0x1 0x0
EEPROM version: 0x11e
iwl_read_ucode() prints this when loading the same firmware:
[ 21.406218] iwlagn 0000:03:00.0: firmware: requesting iwlwifi-5000-2.ucode
[ 21.453118] iwlagn 0000:03:00.0: loaded firmware version 8.24.2.12
Note that I have no documentation on the intended usage of the
u8 sw_rev[8] array in struct iwl_alive_resp. sw_rev[0] and sw_rev[1]
have been switched to make the output match iwl_read_ucode(). Nothing
more, nothing less.

Ah, I see. Yes, that looks even better. I feel a bit stupid for not
checking iwlwifi-2.6.git before sending this. Thanks for your patience.

Since 2.6.31 is considered a done deal and this is surely not the
required "earth shattering" fix (see [1]) I cannot push this as a fix
into Linus's repo at this time. This display problem will not exist in
2.6.32.

Hi Bjørn,
Which kernel/repo is your patch based on?

Correct. Since this information is already printed in the system logs we
determined that the version sysfs file is not needed and has been
removed. Your patch is thus not relevant to the recent code
(wireless-testing repository).
Here is the patch for your reference:
commit 44f313c2e63dcf93b17e6a43769105e487e2e49d

iwlwifi: remove duplicated version info from sysfs
version info in sysfs had been determined to be unnecessary as it
is already provided in syslog info. nvm version is added to syslog
version info as a debug level message to provide all info that was
in the version sysfs data.

Oh, sorry for not including that vital information. I'm afraid it is
against Linus' tree at
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
and not any of the wireless/networking trees.
"git log drivers/net/wireless/iwlwifi/iwl-agn.c" shows this as the last
