Subject: [PATCH] net: dsa: b53: do not enable RGMII delay on bcm63xx
|
|
|
|
bcm63xx's RGMII ports are always in MAC mode, never in PHY mode, so we
|
|
shouldn't enable any delays and let the PHY handle any delays as
|
|
necessary.
|
|
|
|
This fixes using RGMII ports with normal PHYs like BCM54612E, which will
|
|
handle the delay in the PHY.
|
|
|
|
Fixes: ce3bf94871f7 ("net: dsa: b53: add support for BCM63xx RGMIIs")
