Subject: [PATCH net-next 3/3] net: dpaa_eth: simplify dpaa_ioctl()

phylink_mii_ioctl() handles multiple ioctls in addition to just
SIOCGMIIREG: SIOCGMIIPHY, SIOCSMIIREG. Don't filter these out.

Also, phylink can handle the case where net_dev->phydev is NULL (like
optical SFP module, fixed-link). Be like other drivers and let phylink
do so without any driver-side call filtering.
