From dbdcc2620b627072657bd8df4422d11ae3aa056b Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Mon, 24 Nov 2014 15:04:46 +0100 Subject: [PATCH] ath10k: remove extra_tx_headroom Comment was out-of-date. The headroom is no longer necessary because HTT Tx fragment list is stored in dma pool item associated with each sk_buff.
