--------------------------------
[ Upstream commit e1a9faddffe7e555304dc2e3284c84fbee0679ee ]
The CAT875 sub board from Silicon Linux uses a Realtek PHY.
The phy driver commit bbc4d71d63549bcd003 ("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.
