From bca4ce4f75215333febcb09b2508344e63c688cb Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 24 Sep 2015 16:59:46 +0200 Subject: ath9k: declare required extra tx headroom commit 029cd0370241641eb70235d205aa0b90c84dce44 upstream. ath9k inserts padding between the 802.11 header and the data area (to align it). Since it didn't declare this extra required headroom, this led to some nasty issues like randomly dropped packets in some setups.
