STRUCT MXL862XX_RMON_PORT_CNT(9)

💅 NAME 💅

ok so bestie, gather round: struct mxl862xx_rmon_port_cnt — it's the RMON counters for a port. yes, all of them. every single one. she's thorough ✨

this is a Linux kernel API page, from the Kernel API Manual, so it's giving "I live in drivers/net/dsa/mxl862xx" energy 🎀

🌸 DESCRIPTION 🌸

✨ Members ✨

okay so every field, one by one, no skipping, I promised 🫶

• port_type — the port type for counter retrieval (peep enum mxl862xx_port_type — she's in SEE ALSO too)
• port_id — ethernet port number, and it's zero-based, so the first port is 0, not 1, don't come for me
• sub_if_id_group — sub-interface ID group
• pce_bypass — separates the CTP Tx counters when PCE is bypassed
• rx_extended_vlan_discard_pkts — discarded at extended VLAN operation
• mtu_exceed_discard_pkts — discarded because the MTU got exceeded 😭
• tx_under_size_good_pkts — Tx undersize (<64) packet count
• tx_oversize_good_pkts — Tx oversize (>1518) packet count
• rx_good_pkts — received good packet count

okay that's the whole page, you ate that 💖 this one's from ./drivers/net/dsa/mxl862xx, Kernel API Manual, dated October 2026 — so when you see that date on the page, that's just her birthday, don't overthink it. bye bestie, go count some packets 🦋✨🎀
