From 1f6e0baa703d31002c312c3e423c108b04325df0 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Tue, 11 Feb 2020 13:26:04 +0100 Subject: mac80211: allow setting queue_len for drivers not using wake_tx_queue Currently a mac80211 driver can only set the txq_limit when using wake_tx_queue. Not all drivers use wake_tx_queue. This patch adds a new element to wiphy allowing a driver to set a custom tx_queue_len and the code that will apply it in case it is set. The current default is 1000 which is too low for ath11k when doing HE rates.
