STRUCT MXL862XX_VF_BLOCK(9)

💖 NAME 💖

okay so bestie, this is struct mxl862xx_vf_block(9) from the Kernel API Manual, and it's literally the per-port VLAN Filter block — that's the whole name, no cap. iconic little descriptor, honestly 🫶

✨ SYNOPSIS ✨

       struct mxl862xx_vf_block {
           bool allocated;
           u16 block_id;
           u16 block_size;
           u16 active_count;
           struct list_head vids;
        };

🎀 Members 🎀

• allocated — whether the HW block has been allocated via VLANFILTER_ALLOC. basically the “is this thing claimed yet?” flag, fr fr.
• block_id — HW VLAN Filter block ID from VLANFILTER_ALLOC. the actual ID handed back by the hardware, iykyk.
• block_size — total entries allocated in this block. the full size of the block, periodt.
• active_count — number of ALLOW entries at indices [0, active_count). The bridge port config sends max(active_count, 1) as block_size to narrow the HW scan window. discard_unmatched_tagged handles frames outside this range. highkey important detail, don't skip it bestie 😭
• vids — list of mxl862xx_vf_vid entries programmed in this block. the little roster of vids chilling in here 🦋
