Subject: [PATCH net-next 15/15] net: mvpp2: set the GMAC, XLG MAC, XPCS and MPCS in reset when a port is down
This patch adds calls in the stop() helper to ensure both MACs and
both PCS blocks are set in reset when the user manually sets a port
down. This is done so that we have the exact same block reset states at
boot time and when a port is set down.
