Subject: [PATCH] ath10k: support use of channel 173
Git-commit: 38441fb6fcbb97817dff5c012609860a2b39c3e9
Patch-mainline: v4.19-rc1
References: FATE#326906
The India regulatory domain allows CH 173, so add that to the
available channel list. I verified basic connectivity between
a 9880 and 9984 NIC.
