STRUCT FC_EXCH_MGR_ANCHOR(9)

💖 struct fc_exch_mgr_anchor(9) 💖

okay bestie, welcome to the Kernel API Manual — we are looking at struct fc_exch_mgr_anchor, and it is giving primary structure for list of EMs. main character energy fr fr 👑

---

🌸 NAME 🌸

struct fc_exch_mgr_anchor — primary structure for list of EMs. that’s the whole vibe: the headliner struct for keeping a list of EMs. 🫶

---

✨ SYNOPSIS ✨

       struct fc_exch_mgr_anchor {
           struct list_head ema_list;
           struct fc_exch_mgr *mp;
           bool (*match)(struct fc_frame *);
        };

🫶 Members 🫶

• ema_list — Exchange Manager Anchor list 🎀
• mp — Exchange Manager associated with this anchor 🔥
• match — Routine to determine if this anchor's EM should be used 👑

---

💖 Description 💖

When we walk the list of anchors, the match routine will be called for each anchor to determine if that EM should be used. it’s giving matchmaker energy 💅 The last anchor in the list will always match to handle any exchanges not handled by other EMs — no cap. The non-default EMs would be added to the anchor list by HW that provides offloads. 🔥

bestie, remember the anchor-list rule: the last anchor always matches, so it catches whatever the other EMs didn’t. periodt. 💀
