ice_aq_list_caps(9)

okay so bestie, this is ice_aq_list_caps(9) from the Kernel API Manual, and it’s giving “ask firmware what capabilities it has” energy 💅✨ no cap, we’re keeping every detail.

💖 NAME 💖

ice_aq_list_caps — query function/device capabilities 🎀

✨ SYNOPSIS ✨

the signature is literally:

int ice_aq_list_caps (struct ice_hw *hw , void *buf , u16 buf_size , u32
       *cap_count , enum ice_adminq_opc opc , struct ice_sq_cd *cd );

🎀 ARGUMENTS 🎀

okay so the little cast of characters:

• hw — pointer to the HW struct.
• buf — a buffer to hold the capabilities.
• buf_size — size of the buffer.
• cap_count — if not NULL, set to the number of capabilities reported.
• opc — capabilities type to discover, device or function.
• cd — pointer to command details structure or NULL.

🦋 DESCRIPTION 🦋

Get the function (0x000A) or device (0x000B) capabilities description from firmware and store it in the buffer. periodt.

If the cap_count pointer is not NULL, then it is set to the number of capabilities firmware will report. count check slay ✨

⚠️ heads up bestie: if the buffer size is too small, it is possible the command will return ICE_AQ_ERR_ENOMEM. The cap_count will still be updated in this case. It is recommended that the buffer size be set to ICE_AQ_MAX_BUF_LEN (the largest possible buffer that firmware could return) to avoid this.
