Apparently this also fixes some weird issues with qca6174 hw2.1 notably: - ath10k causing disconnecting of other devices in a BSS - random Fw crashes Both problems started to happen because c17c997d5613 enabled monitor vdev by default on STA interfaces. It seems that qca6174 hw2.1 firmware has issues similar to those of qca988x 999.999.0.636 regarding monitor vdev opration. Also, I've made a typo in the subject. I'll post v2 with subject fixed and extended commit log later.
