phy_port_filter_supported(9)

🌸 NAME 🌸

okay so bestie, this page is phy_port_filter_supported(9) from the Kernel API Manual, and its whole job is literally to make sure that port->supported match port->mediums. no cap. 💅

✨ SYNOPSIS ✨

void phy_port_filter_supported (struct phy_port *port );

🎀 ARGUMENTS 🎀

• port — the port that’s getting filtered. that’s the one. 🫶

🦋 DESCRIPTION 🦋

so picture this: you’ve just updated a port’s mediums to a more restricted subset. this helper is the bestie who swoops in afterward and makes sure port->supported only contains linkmodes that are compatible with port->mediums. it’s giving a vibe check for supported linkmodes, and it does not let the incompatible ones crash the party. 🔥
