From 0c094c77ce9c338adc08d6d71b2d92a7761992b8 Mon Sep 17 00:00:00 2001 From: Franky Lin Date: Tue, 22 Nov 2011 17:21:46 -0800 Subject: [PATCH] brcm80211: fmac: discard packet received when net device not registered A new feature in the dongle firmware requires a handshake during firmware intialization. The request is sent in event packets which the host driver is not able to handle before any net device registered. Discard those packets as the context for handling it is missing. The initialization handler will be added as part of feature support code in the future. Signed-off-by: Franky Lin Signed-off-by: John W.
