From db1a052b73f7c97f9e8b21f3f19a92313ed2acb1 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Mon, 29 Mar 2010 20:07:11 -0700 Subject: [PATCH] ath9k: split out access to tx status information This patch passes in a pointer to the ath_tx_status data structure for functions that need it, instead of letting them grab it directly from the ath_desc struct. This is useful for making it possible to allocate the intermediate tx status data separately. Signed-off-by: Felix Fietkau Signed-off-by: John W.
