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. > > Signed-off-by: Serge Semin <fancer.lancer@...il.com> These patches do not apply to the current net GIT tree, please respin.
