Hi Wey-Yi,
I wonder what the following commit is used for:
commit c6fa17ed3fadaf056173c409c0877df428a152ec

iwlwifi: read multiple MAC addresses
Some devices may have multiple MAC
addresses in their EEPROM, read them
and advertise them to cfg80211.
I was trying to debug wireless issues, and noticed that I had two MAC
addresses with only the last bit being different:
$ cat /sys/class/ieee80211/phy0/addresses
00:23:14:xx:xx:x8
00:23:14:xx:xx:x9
Looking at a dump provided by /sys/kernel/debug/cfg80211/phy0/iwlwifi/data/nvm,
I see that the 16-bit word at 0x98 contains the value 4. What does this mean?
Can this break something?
If you are interested, the wireless card I own is a Centrino Advanced-N 6200
(device ID 422c, rev 35). I can reproduce this behaviour on Linux 3.4.2, 3.5-
rc1 (the wireless testing tree from 2012-06-11) and 3.3.5.
Regards,
Peter
