💖 fm10k_update_xc_addr_pf(9) 💖

okay so bestie, welcome to the Kernel API Manual corner of the group chat 👑 this one's a single function page, and it's lowkey the vibe-checker that tells your network switch "hey, add/remove this address for me, mkay?" 🎀

✨ NAME ✨

fm10k_update_xc_addr_pf — literally just: Update device addresses 💅 no cap, that's the whole assignment.

---

🦋 SYNOPSIS 🦋

s32 fm10k_update_xc_addr_pf (struct fm10k_hw *hw , u16 glort , const u8
       *mac , u16 vid , bool add , u8 flags );

it's giving "small signature, big responsibilities" ngl 🌸

🍓 ARGUMENTS 🍓

• hw — pointer to the HW structure 🫶 like, the hardware said "handle me gently" and this is the handle.
• glort — the base resource tag for this request 🌈 (yes it's called glort, no we didn't pick the name, moving on ✈️)
• mac — the MAC address to add/remove from the table 👑 the actual star of the show fr fr.
• vid — the VLAN ID to add/remove from the table 🧚 tag it or untag it, that's the assignment.
• add — Indicates if this is an add or remove operation 💀 iconic boolean behaviour, we love a yes/no moment.
• flags — the flags field, used to indicate add and secure 🔥 security girlies rise.

💜 DESCRIPTION 💜

so the way that this works 😭 this function generates a message to the Switch API asking, very politely but very insistently, that the given logical port add or remove the given L2 MAC/VLAN address from the table ✨

that's it. that's the whole plot. a request gets built, the Switch API gets it, the address gets added or removed, and everybody slays 💅

mwah 💋 that's the page. source/version vibes: this is the Kernel API Manual, straight out of the kernel source tree at ./drivers/net/ethernet/intel/f... (the path got a lil truncated in the footer, she's shy 🙈), and the date on the footer says October 2026 🗓️✨ go forth and update those addresses bestie, iykyk 🫶💖
