From dc28e078432c0402665cffe8dd0365672cc94b6f Mon Sep 17 00:00:00 2001 From: Shaul Triebitz Date: Thu, 28 Feb 2019 17:17:58 +0200 Subject: [PATCH] iwlwifi: mvm: set 512 TX queue slots for AX210 devices AX210 devices support 256 BA (256 MPDUs in an AMPDU). The firmware requires that the number of TFDs will be minimum twice as big as the BA size (2 * 256 = 512).
