lpfc_hba_down_link(9)

🌸 NAME 🌸

okay so welcome to the lpfc_hba_down_link(9) page from the Kernel API Manual, bestie 💖 — this routine downs the FC link. that’s the whole main-character job: link goes down, periodt. 💅

✨ SYNOPSIS ✨

int lpfc_hba_down_link (struct lpfc_hba *phba , uint32_t flag );

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure.
• flag — mailbox command issue mode — either MBX_POLL or MBX_NOWAIT.

🦋 DESCRIPTION 🦋

This routine will issue the DOWN_LINK mailbox command call. it’s available to other drivers through the lpfc_hba data structure for use to stop the link.

Return code 0 - success. Any other value - error. that’s it, no cap. ✨
