lpfc_els_retry(9)

💅 lpfc_els_retry(9) — Kernel API Manual, bestie edition 💅

Okay so this is lpfc_els_retry(9) from the Kernel API Manual, and it's giving “should we run this ELS command back or nah?” energy. Let's get into it, no cap. 🦋

✨ NAME ✨

lpfc_els_retry — make retry decision on an els command iocb. Like, the whole vibe is deciding whether a failed ELS command gets another shot. 💖

💫 SYNOPSIS 💫

int lpfc_els_retry (struct lpfc_hba *phba , struct lpfc_iocbq *cmdiocb , struct lpfc_iocbq *rspiocb );

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure. The hba in question, slay. 👑
• cmdiocb — pointer to lpfc command iocb data structure. The command-side iocb. 💌
• rspiocb — pointer to lpfc response iocb data structure. The response-side iocb. 💌

🦋 DESCRIPTION 🦋

Okay so this routine makes a retry decision on an ELS command IOCB, which has failed. Not me being dramatic — that's literally the job. Main character energy, honestly.

The following ELS IOCBs use this function for retrying the command when a previously issued command responded with error status: FLOGI, PLOGI, PRLI, ADISC and FDISC. iykyk ✨

Based on the ELS command type and the returned error status, it makes the decision whether a retry shall be issued for the command, and whether a retry shall be made immediately or delayed. In the former case, the corresponding ELS command issuing-function is called to retry the command. In the later case, the ELS command shall be posted to the ndlp delayed event and delayed function timer set to the ndlp for the delayed command issuing. 🫶

Return code:

• 0 — No retry of els command is made.
• 1 — Immediate or delayed retry of els command is made.

Bestie, that's the whole decision tree: 0 means no retry, 1 means immediate or delayed retry. Clean, iconic, periodt. 💅
