From: Chen-Yu Tsai <w...@csie.org>The Ethernet PHY on the Cubietruck has the RX and TX delays enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins. Fix the phy-mode description to correct reflect this so that the implementation doesn't reconfigure the delays incorrectly. This happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config").

I upgraded kernels yesterday and saw that networking had stopped working. I can confirm that this patch fixes the problem and restores connectivity on my Cubietruck. I also verified the information with the schematics, and it looks alright to me :)
