As part of the effort of making U-Boot work with the same device tree as Linux, there is an issue with the "xfi" phy-mode. To be precise, in Linux there was a discussion (for those who have time to read: https://lore.kernel.org/netdev/1576768881-24971-2-git-send-email-madalin.bucur@oss.nxp.com/) which led to a patch: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=c114574ebfdf42f826776f717c8056a00fa94881 TL;DR: "xfi" was standardized in Linux as "10gbase-r". This patch changes the relevant occurrences in U-Boot to use "10gbase-r" instead of "xfi" wherever applicable.
