Subject: [PATCH] net: dsa: b53: allow RGMII for bcm63xx RGMII ports
|
|
|
|
Add RGMII to supported interfaces for BCM63xx RGMII ports so they can be
|
|
actually used in RGMII mode.
|
|
|
|
Without this, phylink will fail to configure them:
|
|
|

[ 3.580000] b53-switch 10700000.switch GbE3 (uninitialized): validation of rgmii with support 0000000,00000000,00000000,000062ff and advertisement 0000000,00000000,00000000,000062ff failed: -EINVAL
|
|
[ 3.600000] b53-switch 10700000.switch GbE3 (uninitialized): failed to connect to PHY: -EINVAL
|
|
[ 3.610000] b53-switch 10700000.switch GbE3 (uninitialized): error -22 setting up PHY for tree 0, switch 0, port 4
