From e11e8729fafd3dc49397c28f320ac3b2d483abbc Mon Sep 17 00:00:00 2001 From: Romain Perier Date: Thu, 3 Aug 2017 09:49:03 +0200 Subject: [PATCH] net: arc_emac: Add support for ndo_do_ioctl net_device_ops operation This operation is required for handling ioctl commands like SIOCGMIIREG, when debugging MDIO registers from userspace. This commit adds support for this operation. Signed-off-by: Romain Perier Signed-off-by: David S.
