From 7bb4568372856688bc070917265bce0b88bb7d4d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 24 Feb 2011 14:42:06 +0100 Subject: mac80211: make tx() operation return void The return value of the tx operation is commonly misused by drivers, leading to errors. All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211. Note that this also fixes a bug in ath9k_htc, the old "return -1" there was wrong.
