From d6bda6671f8fda961f6cce95e644f6a14fe5bd2a Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Wed, 12 Nov 2014 13:30:20 +0200 Subject: [PATCH] iwlwifi: mvm: rs: consider a missing BA as a single tx failure The fw now indicates missing BA with ampdu_ack_len=0. This will make the whole aggregation being marked as failed, although it's most likely not the case (and only the BA itself was failed). Consider this case as a single tx failure.
