fcoe_ctlr_select(9)

💅 fcoe_ctlr_select(9) — Kernel API Manual ✨

🌸 NAME 🌸

fcoe_ctlr_select — select the best FCF (if possible) 💖

✨ SYNOPSIS ✨

struct fcoe_fcf * fcoe_ctlr_select (struct fcoe_ctlr *fip );

🎀 ARGUMENTS 🎀

• fip — the FCoE controller. That's the whole argument, bestie 🫶

💫 DESCRIPTION 💫

Returns the selected FCF, or NULL if none are usable. That's it — if nobody is usable, you get NULL, no cap.

If there are conflicting advertisements, no FCF can be chosen. 🚫 Like, they're fighting in the group chat and nobody gets crowned.

If there is already a selected FCF, this will choose a better one or an equivalent one that hasn't already been sent a FLOGI. 👑✨

Called with lock held. 🔒 That's the vibe — the lock is already held when this runs.
