From 44713b1da5a78d722dc0c03a87dc9ddf46668f80 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Mon, 26 Mar 2007 00:59:47 +0100 Subject: [PATCH] [PATCH] zd1211rw: Don't handle broken frames in monitor mode Using monitor mode, Johannes Berg observed out that lots of corrupted and otherwise invalid frames were being passed to the host. When in monitor mode we were disabling the hardware filtering here, but this is not how monitor mode should work. Signed-off-by: Daniel Drake Signed-off-by: John W.
