From: Florian Fainelli <f.fainelli@gmail.com>
commit 0cdefd5b5485ee6eb3512a75739d09a4090176ed upstream.
The CPU port of the BCM53125 is configured with RGMII (no delays) but
this should actually be RGMII with transmit delay (rgmii-txid) because
STMMAC takes care of inserting the transmitter delay. This fixes
occasional packet loss encountered.
