ib_init_ah_from_mcmember(9)

💖 NAME 💖

okay so bestie, welcome to ib_init_ah_from_mcmember — Kernel API Manual edition, and it does exactly one iconic thing: it initializes address handle attributes based on an SA multicast member record. that's the whole vibe. ✨

✨ SYNOPSIS ✨

int ib_init_ah_from_mcmember (struct ib_device *device , u32 port_num ,
struct ib_sa_mcmember_rec *rec , struct net_device *ndev , enum
ib_gid_type gid_type , struct rdma_ah_attr *ah_attr );

🎀 ARGUMENTS 🎀

so here's the thing, bestie — the original page literally says nothing about these. not a single crumb. all of them are marked:

-- undescribed --

like, the documentation really said "figure it out yourself queen 💅". so here they are, in order, with their honest-to-god status:

• device — -- undescribed -- 🫠
• port_num — -- undescribed -- 🫠
• rec — -- undescribed -- 🫠
• ndev — -- undescribed -- 🫠
• gid_type — -- undescribed -- 🫠
• ah_attr — -- undescribed -- 🫠

ngl i'm not gonna invent lore for these. the manual page ate and left zero notes. 😭 if you need the deets, go read the source, because this page is not the main character here.

🦋 SEE ALSO 🦋

go touch some related kernel lore, bestie:

• Kernel file ./include/rdma/ib_sa.h
• struct sa_path_rec_roce(9)
• ib_sa_register_client(9)
• ib_sa_unregister_client(9)

🌸 k that's the whole page, no cap. this lil gem lives in ./include/rdma, it's dated October 2026, and it's filed under the Kernel API Manual — so like, go forth and initialize those ah attributes, bestie. periodt. 👑💜
