From: Maxime Chevallier Date: Fri, 7 Mar 2025 17:36:08 +0000 (+0100) Subject: net: phylink: Add a mapping between MAC_CAPS and LINK_CAPS X-Git-Tag: v6.15-rc1~160^2~96^2~2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3bea75002a05b86bf4d87773c456f39f7693f5c4;p=thirdparty%2Fkernel%2Flinux.git net: phylink: Add a mapping between MAC_CAPS and LINK_CAPS phylink allows MAC drivers to report the capabilities in terms of speed, duplex and pause support. This is done through a dedicated set of enum values in the form of the MAC_ capabilities. They are very close to what the LINK_CAPA_xxx can express, with the difference that LINK_CAPA don't have any information about Pause/Asym Pause support. To prepare converting phylink to using the phy_caps, add the mapping between MAC capabilities and phy_caps. While doing so, we move the phylink_caps_params array up a bit to simplify future commits.
