From 0c9cc640225f4bd7c9aad87b1431bd8d9a29b338 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Mon, 30 Nov 2009 18:12:49 +0100 Subject: [PATCH] mwl8k: allow more time for firmware commands to complete Some firmware commands can under some circumstances take more than 2 seconds to complete. This patch bumps the timeout up to 10 seconds, and prints a message whenever a command takes more than 2 seconds. Signed-off-by: Lennert Buytenhek Signed-off-by: John W.
