| iwlagn: fix command queue timeout |
| |
| If the command queue is constantly busy, |
| which can happen in P2P, the hangcheck |
| timer will frequently find a command in |
| it and will eventually reset the device |
| because nothing sets the timestamp for |
| this queue when commands are processed. |
| |
| Fix this by setting the timestamp when |
| a command completes. |
| |
| iwlegacy does not support P2P, but this patch fix possible |
| unneeded hardware resets, hence is needed. |
