lpfc_sli4_async_grp5_evt(9)

🦋 lpfc_sli4_async_grp5_evt(9) 🦋

okay bestie, welcome to the Kernel API Manual entry for lpfc_sli4_async_grp5_evt. This one is giving “async grp5 event handler that knows exactly what it’s doing,” and we’re gonna go through it together, no cap. 💖

🌸 NAME 🌸

lpfc_sli4_async_grp5_evt — process the asynchronous group5 event. 💅

✨ SYNOPSIS ✨

okay so the signature is literally this, exactly:

void lpfc_sli4_async_grp5_evt (struct lpfc_hba *phba , struct
lpfc_acqe_grp5 *acqe_grp5 );

🫶 ARGUMENTS 🫶

Two arguments, both pointers, both important:

• phba — pointer to lpfc hba data structure.
• acqe_grp5 — pointer to the async grp5 completion queue entry.

💫 DESCRIPTION 💫

This routine handles the SLI4 asynchronous grp5 event. A grp5 event is an asynchronous notification of a logical link speed change. The Port reports the logical link speed in units of 10Mbps.

So it’s a link-speed update situation, and the units are 10Mbps — iconic, specific, and not to be forgotten. 💅
