[ Upstream commit e1a9faddff ]
The CAT875 sub board from Silicon Linux uses a Realtek PHY.
The phy driver commit bbc4d71d63 ("net: phy: realtek: fix
rtl8211e rx/tx delay config") introduced NFS mount failures. Now it
needs both rx/tx delays for the NFS mount to work.
This patch fixes the NFS mount failure issue by adding "rgmii-id" mode
to the avb device node.
