[PATCH 1/2] net: mvpp2: fix 10 Mbit/s usage

[Thomas Petazzoni]

This commit is similar to commit 4d12bc63ab5e ("net: mvneta: fix
operation in 10 Mbit/s mode"), but this time for the mvpp2 driver. The
driver was properly taking into account the 1 Gbit/s and 100 Mbit/s
speeds, but not the 10 Mbit/s, which was handled as 100
Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the
MVPP2_GMAC_AUTONEG_CONFIG register must remain cleared to allow 10
Mbit/s operation. This commit therefore fixes 10 Mbit/s operation.

[PATCH 2/2] net: mvpp2: implement ioctl() operation for PHY ioctls

[Thomas Petazzoni]

This commit implements the ->ndo_do_ioctl() operation so that the
PHY-related ioctl() calls can work from userspace, which allows
applications like mii-tool or mii-diag to do their job.
