Subject: [PATCH net-next 0/3] net: phylink: support !autoneg configuration
 for SFPs

This series comes from discussion during a patch series that was posted
at the beginning of April, but these patches were never posted (I was
too busy!)

We restrict ->sfp_interfaces to those that the host system supports,
and ensure that ->sfp_interfaces is cleared when a SFP is removed. We
then add phylink_sfp_select_interface_speed() which will select an
appropriate interface from ->sfp_interfaces for the speed, and use that
in our phylink_ethtool_ksettings_set() when a SFP bus is present on a
directly connected host (not with a PHY.)
