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 <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
