From the very beginning it use only tx delays. However the phy driver commit bbc4d71d63549bcd003 ("net: phy: realtek: fix rtl8211e rx/tx delay config") introduced NFS mount failure. Now it needs rx delay inaddition to tx delay for NFS mount to work. This patch fixes NFS mount failure issue by adding MAC internal rx delay.
