💅 lpfc_els_rcv_rls — Kernel API Manual ✨

okay bestie, so this is a page from the Kernel API Manual and it's about lpfc_els_rcv_rls, and yes we're getting into Fibre Channel ELS brainrot today. stay with me, it's gonna slay 🎀

🌸 NAME 🌸

lpfc_els_rcv_rls — process an unsolicited rls iocb, no cap 💖

⭐ SYNOPSIS ⭐

int lpfc_els_rcv_rls (struct lpfc_vport *vport , struct lpfc_iocbq
*cmdiocb , struct lpfc_nodelist *ndlp );

like literally that's the whole signature, she's giving three pointers and an int return 🦋

🎀 ARGUMENTS 🎀

  • vport — pointer to a host virtual N_Port data structure. that's your vport bestie, she's the whole vibe 🫶
  • cmdiocb — pointer to lpfc command iocb data structure. this is the iocb carrying the command, main character energy fr fr 💅
  • ndlp — pointer to a node-list data structure. the node list entry for the port we're dealing with 🌸

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this routine processes a Read Link Status (RLS) IOCB that came in as an ELS unsolicited event. she's just out here handling unsolicited mail, iconic.

First thing she does is a vibe check on the remote port state 👀. If the remote port is not in NLP_STE_UNMAPPED_NODE state or NLP_STE_MAPPED_NODE state, she invokes the lpfc_els_rsl_reject routine to send the reject response. not me rejecting them 💀 that's literally the behavior.

Otherwise (so, if it is in one of those two states), she issues the MBX_READ_LNK_STAT mailbox command for reading the HBA link statistics. lowkey the whole point 🍓

And just so you know — it's for the callback function lpfc_els_rsp_rls_acc, which is set to the MBX_READ_LNK_STAT mailbox command, to actually send out the RPL Accept (ACC) response. she does the setup, the callback does the sending. teamwork periodt ✨

Return codes:

  • 0 — Successfully processed rls iocb (currently always return 0) 😌 she literally never misses, it's always 0
ngl the original doc says the reject routine is lpfc_els_rsl_reject — spelling exactly as written here, and the accept callback is lpfc_els_rsp_rls_acc. two different spellings, both intentional in this page, don't come for me 🙈
