From f40bff4239d45ac061044a8a79cf6868c62df345 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Sat, 21 Mar 2015 11:29:37 +0100 Subject: [PATCH] cx82310_eth: wait for firmware to become ready When the device is powered up, some (older) firmware versions fail to work properly if we send commands before the boot is complete (everything is OK when the device is hot-plugged). The firmware indicates its ready status by putting the link up. Newer firmwares delay the first command so they don't suffer from this problem. They also report the link being always up. Wait for firmware to become ready (link up) before sending any commands and/or data. This also allows lowering CMD_TIMEOUT value to a reasonable time. Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions. Signed-off-by: Ondrej Zary Signed-off-by: David S. Miller --- Reading git-format-patch failed
