From 80a284bd154ee3a9d38ee9c264a3a2bf6114385e Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Sun, 19 Sep 2010 13:01:02 +0300 Subject: [PATCH] staging: w35und: Use NETDEV_TX_BUSY if MLMESendFrame fails This patch changes MLMESendFrame to return NETDEV_TX_BUSY if MLME frame is in use so that wbsoft_tx() doesn't blindly return NETDEV_TX_OK in that case.
