Hi,

I noticed my wireless interface can't get up with linux v4.14 and the
kernel log is flooded with firmware errors:

iwlwifi 0000:03:00.0: Firmware error during reconfiguration - reprobe!
iwlwifi 0000:03:00.0: FW error in SYNC CMD DQA_ENABLE_CMD

and

ieee80211 phy63: Hardware restart was requested.

The wireless controller is: Intel Corporation Wireless 7260 (rev 83)
Firmware used is: iwlwifi-7260-17

Everything works fine with v4.13.12.

I didn't have time today to bisect for the offending commit. Full log
uploaded[1].

Best regards,
Bartosz Golaszewski
