💖 fcoe_ctlr_send_keep_alive(9) 💖

okay bestie, welcome to the Kernel API Manual page for fcoe_ctlr_send_keep_alive(9) — literally the function that sends a keep-alive to the selected FCF. this is giving low-level FCoE friendship-maintenance energy, and we're gonna read it together 🫶

🌸 NAME 🌸

fcoe_ctlr_send_keep_alive — Send a keep-alive to the selected FCF 💌

✨ SYNOPSIS ✨

       void fcoe_ctlr_send_keep_alive (struct fcoe_ctlr *fip , struct fc_lport
       *lport , int ports , u8 *sa );

🎀 ARGUMENTS 🎀

• fip — The FCoE controller to send the FKA on ✨
• lport — libfc fc_lport to send from 💅
• ports — 0 for controller keep-alive, 1 for port keep-alive 🎀
• sa — The source MAC address 🦋

🦋 DESCRIPTION 🦋

okay so there are two keep-alive vibes, and they are not the same:

A controller keep-alive is sent every fka_period (typically 8 seconds). The source MAC is the native MAC address. 👑

A port keep-alive is sent every 90 seconds while logged in. The source MAC is the assigned mapped source address. The destination is the FCF's F-port. 💫
