From 8538823f7c692c98e8b7e19cb580faa56e25e89f Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Mon, 17 Dec 2007 15:41:30 -0500 Subject: [PATCH] libertas: discard DEFER responses to commands; let the timeout trigger When the firmware returns 0x0004, it wants us to try again later. We can achieve that simply by throwing out the response and letting the command timeout code kick in. Signed-off-by: David Woodhouse Signed-off-by: John W.
