ethtool_link...el_link_mode(9)

💖 ethtool_link...el_link_mode(9) 💖

okay so this little page is from the Kernel API Manual, and we're about to make a link-mode bit get gone. no cap. 💅

NAME

ethtool_link_ksettings_del_link_mode — clear bit in link_ksettings link mode mask. That's literally the whole vibe: it clears a bit in the link_ksettings link mode mask. ✨

SYNOPSIS

ethtool_link_ksettings_del_link_mode (ptr , name , mode );

ARGUMENTS

• ptr — pointer to struct ethtool_link_ksettings. Like, hand over the struct, bestie. 🫶
• name — one of supported/advertising/lp_advertising. Pick your lane.
• mode — one of the ETHTOOL_LINK_MODE_*_BIT (not atomic, no bound checking). So that's the mode; don't get cute with it.

⚠️ real talk: mode is not atomic and has no bound checking. The manpage says it, I'm just repeating it with feeling. 😭
