From ad846aa52ca7b7ec6b99a8b13c4ce0bbe7b15b7f Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Mon, 14 Mar 2016 01:09:53 +0300 Subject: [PATCH] sh_eth: do not call netif_start_queue() from sh_eth_dev_init() Iff sh_eth_phy_start() call fails in sh_eth_open(), the netif_start_queue() call done by sh_eth_dev_init() is not undone. In order to deal with that, stop calling netif_start_queue() from there, so that it can be called only when the device is fully opened and sh_eth_dev_init() only deals with the hardware initialization, symmetrically to sh_eth_dev_exit()...
