📦 version 7.3.1, in nixpkgs unstable

💖 fcoe_ctlr_mode_set(9) 💖

okay so bestie, this is fcoe_ctlr_mode_set(9) from the Kernel API Manual. It's short, it's specific, and every detail is doing its little main-character moment. Let's go. 🫶

✨ NAME ✨

fcoe_ctlr_mode_set — set or reset the ctlr's mode. That's the whole vibe. 💅

🎀 SYNOPSIS 🎀

void fcoe_ctlr_mode_set (struct fc_lport *lport , struct fcoe_ctlr *fip
, enum fip_mode fip_mode );

🦋 ARGUMENTS 🦋

  • lport — the local port to be (re)configured. literally the local port getting its little refresh. ✨
  • fip — the FCoE controller whose mode is changing. it's giving "main character controller." 👑
  • fip_mode — the new fip mode. the fresh mode in question. 🍓

🌈 DESCRIPTION 🌈

Okay so here's the note, and it is important, bestie: we shouldn't be changing the libfc discovery settings (fc_disc_config) while an lport is going through the libfc state machine. no cap. 😭

The mode can only be changed when a fcoe_ctlr device is disabled, so that should ensure that this routine is only called when nothing is happening. That's the whole safety vibe check. 💖

tl;dr energy: don't be messing with fc_disc_config mid-libfc-state-machine, and remember the mode-change situation only happens when a fcoe_ctlr device is disabled. periodt. 💅
