[RFC PATCH v2 net-next 11/15] net: phylink: support the 25GBase-KR-S and 25GBase-CR-S link modes too

From: Vladimir Oltean
Date: Sat Sep 23 2023 - 09:50:18 EST


Treat the newly introduced subsets of 25GBase-KR and 25GBase-CR the same
way as the fully-featured link modes. The difference only consists in
RS-FEC support.
