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. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S.
