> It has been discovered that RX/TX delays of rtl8211e ethernet PHY
> can be configured via a MDIO register hidden in the extension pages
> layout. Particularly the extension page 0xa4 provides a register 0x1c,
> which bits 1 and 2 control the described delays. They are used to
> implement the "rgmii-{id,rxid,txid}" phy-mode support in patch 1.
> 
> The second patch makes sure the rtl8211f TX-delay is configured only
> if RGMII interface mode is specified including the rgmii-rxid one.
> In other cases (most importantly for NA mode) the delays are supposed
> to be preconfigured by some other software or hardware and should be
> left as is without any modification. The similar thing is also done
> for rtl8211e in the patch 1 of this series.
