STRUCT VIRTCHNL2_RSS_KEY(9)

okay bestie, welcome to struct virtchnl2_rss_key(9) — the Kernel API Manual page that's lowkey all about RSS key info 💖✨

💖 NAME 💖

struct virtchnl2_rss_key - RSS key info. periodt. 💅

✨ SYNOPSIS ✨

struct virtchnl2_rss_key {
    __le32 vport_id;
    __le16 key_len;
    u8 pad;
    u8 key_flex[];
};

No cap, that's the whole struct layout 🫶

👑 Members 👑

• vport_id — Vport id. literally what it says 💅
• key_len — Length of RSS key.
• pad — Padding. iconic little spacer 🎀
• key_flex — RSS hash key, packed bytes. PF/VF sends this message to get or set RSS key. Only supported if both PF/VF and CP drivers set the VIRTCHNL2_CAP_RSS bit during configuration negotiation.

okay bestie, that support condition is not optional — both PF/VF and CP drivers gotta set the VIRTCHNL2_CAP_RSS bit during configuration negotiation, or it's not supported 💀

🌸 Description 🌸

Associated with VIRTCHNL2_OP_GET_RSS_KEY and VIRTCHNL2_OP_SET_RSS_KEY. That's the vibe check for this one ✨
