Subject: [PATCH 004/146] arm64: allwinner: a64: disable the RTL8211E internal
|
|
RX delay on Pine64+
|
|
|
|
Some Pine64+ boards have a broken RTL8211E PHY, which cannot work
|
|
reliably in 1000Base-T mode with default configuration.
|
|
|
|
A solution is passed to Pine64, which is said to be disabling the
|
|
internal RX delay of the PHY.
|
|
|
|
Enable the hack by set the PHY mode to RGMII-TXID.
