lpfc_read_lnk_stat(9)

💖 NAME 💖

okay bestie, welcome to the lpfc_read_lnk_stat(9) page from the Kernel API Manual ✨ the whole vibe is Prepare a mailbox command for reading HBA link stats — that's the name, no cap 💅

✨ SYNOPSIS ✨

void lpfc_read_lnk_stat (struct lpfc_hba * phba , LPFC_MBOXQ_t * pmb );

💜 ARGUMENTS 💜

• phba — pointer to the lpfc hba data structure 🫶
• pmb — pointer to the driver internal queue element for mailbox command 💌

🦋 DESCRIPTION 🦋

so the read link status mailbox command is what you use to read the link status from the HBA, periodt 🔥 Link status includes all link-related error counters — yes, all of them. These counters are maintained by the HBA and originated in the link hardware unit. lowkey important detail: all of these counters wrap 😭 so don't act surprised when they roll over.

this routine prepares the mailbox command for reading out HBA link status. it's giving setup era, not the actual reading era, iykyk 💅
