STRUCT EFX_TC_MAC_PEDIT_ACTION(9)

💅 NAME

struct efx_tc_mac_pedit_action — the mac pedit action fields, bestie. That's it, that's the whole vibe. ✨

Oh and hii, welcome to the Kernel API Manual — this lil page is struct efx_t...pedit_action(9) and it lives rent-free in ./drivers/net/ethernet/sfc. 🫶

---

✨ SYNOPSIS ✨

Okay so here's the struct, and no I did not touch a single character of it, I would never:

struct efx_tc_mac_pedit_action {
    u8 h_addr[ETH_ALEN];
    struct rhash_head linkage;
    refcount_t ref;
    u32 fw_id;
 };

Look at her. Gorgeous. Structurally sound. Main character energy fr fr. 👑

🎀 MEMBERS 🎀

• h_addr — the mac address field of the ethernet header. That's the actual address getting edited, the whole point of the situation. 💖
• linkage — the rhashtable reference. It's the little hookup that keeps this entry chained into the table, lowkey essential. 🔗
• ref — a reference count, type refcount_t. Standard "how many people are holding onto me" situation, we love a counted queen. 🧚
• fw_id — index of this entry in the firmware MAC address table. So like, its seat number in the firmware's own little address book. 🌸

---

🦋 DESCRIPTION 🦋

So the tea is this: MAC address edits are indirected through a table in the hardware. That's it. That's the whole description. The struct is basically a lil handle into the hardware's own MAC address table, and the hardware does the actual editing — we're just here holding a reference and a fw_id pointing at the right slot. No cap. 🫡

Not me being obsessed with indirection — it's giving "don't do the work yourself, let the hardware table handle it" and honestly? Slay. 💅

🌈 SEE ALSO 🌈

Go touch some grass in the kernel file ./drivers/net/ethernet/sfc/tc.h, and then say hi to these besties:

• struct efx_tc_action_set(9)
• enum efx_tc_em_pseudo_type(9)
• struct efx_tc_state(9)

Okay that's the whole page, you ate it, periodt. 💅✨

This iconic lil number comes to you from ./drivers/net/ethernet/sfc, dated October 2026, and yes the manual still calls her struct efx_t...pedit_action(9) because truncation is eternal, iykyk. 🎀🦋💜
