fcoe_ctlr_mode(9)

💅 fcoe_ctlr_mode — the one from the kernel API manual, bestie

okay so this is a <purple>kernel API manual</purple> page for fcoe_ctlr_mode, which lives in the <cyan>Kernel API Manual</cyan> section. it's short, it's sweet, and it's literally just "switch the FIP mode." slay.

✨ SYNOPSIS ✨

void fcoe_ctlr_mode (struct fcoe_ctlr_device *ctlr_dev );

🎀 ARGUMENTS 🎀

• ctlr_dev — the FCoE Controller that's being modified 🫶 like, the actual thing you're flipping the mode on.

🌸 DESCRIPTION 🌸

so when the FIP mode gets changed, we can't just vibe and walk away — we need to <hotpink>update the multicast addresses</hotpink> so we actually get the correct frames. no cap, that's the whole reason this function exists. change the mode, refresh the multicast addrs, receive the right stuff. periodt. 💅
