Subject: [RESEND][PATCH next 2/2] bgmac: use phy_mii_ioctl in ioctl handler

From: Hauke Mehrtens <hauke@...ke-m.de>

This works pretty much the same way, so avoid duplicating the code.

This ports part of Hauke's patch from OpenWrt.

Hauks: I've just dropped
if (!bgmac->phydev)
	return -EINVAL;
as we are guaranteed to have PHY dev.
