From: Liad Kaufman Date: Mon, 23 Oct 2017 12:02:42 +0000 (+0300) Subject: iwlwifi: mvm: support MGMT frames in compressed BA X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=087428d39721c7a721559977444dc7150132ce68;p=linux.git iwlwifi: mvm: support MGMT frames in compressed BA In A000 family, compressed BA notifs can include MGMT frames, so don't fail RXs in such a case. While at it, since in A000 the TID for MGMT frames is 15, treat it in the RX flow as if received TID 8. This way we won't require special handling of this TID.
