Hi,

I hope I'm writing to the right addresses, this is my first kernel bug
report :-)

I regulary build linus' tree from git. One day, my wireless card was
unable to connect to the access point. dmesg showed something like this:

[  122.290949] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 1)
[  122.490158] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 2)
[  122.690057] wlan0: direct probe to 00:15:0c:xx:xx:xx (try 3)
[  122.890031] wlan0: direct probe to 00:15:0c:xx:xx:xx timed out

At first, I thought is was some link quality problem and tried it next
to the access point, but it still didn't work.
I booted another (older) kernel and with this one, the card was able to
connect without any problems.

I bisected the problem and came to commit
062bee448bd539580ef9f64efe50fdfe04eeb103
iwlwifi: set TX_CMD_FLAG_PROT_REQUIRE_MSK in tx_flag

My wireless card is a Intel Corporation Wireless WiFi Link 5100.

Will provide more info if needed.

Florian
