ice_get_rxnfc(9)

ice_get_rxnfc(9) — get those Rx flow classification rules 💅

okay so this is a page from the Kernel API Manual — yes, the kernel, bestie, we're in the networking layer today, and it's giving driver-internals main character energy. Buckle up 🎀

---

NAME

ice_get_rxnfc — the command to get Rx flow classification rules ✨

---

SYNOPSIS

int ice_get_rxnfc (struct net_device *netdev , struct ethtool_rxnfc *cmd
, u32 *rule_locs );

that's the whole signature, no cap — it takes three things and hands you an int back 🫶

---

ARGUMENTS

• netdev — the network interface device structure, aka which netdev we're talking about, bestie, we gotta know 🌸
• cmd — the ethtool rxnfc command. this is the actual ask you're making 🔥
• rule_locs — the buffer to rturn Rx flow classification rules. (yes, rturn — that's exactly how it's spelled in the source, i'm not fixing it, i'm just reporting it 💀) so like… this is where the rule locations come back out to you 🙈

---

DESCRIPTION

Returns Success if the command is supported. that's it. that's the whole vibe check — command supported? slay, Success. not supported? well. 👑

that's the whole page, bestie, you ate it up 🍓

ngl there's not a lot of drama here — it's a getter, it returns Success if the command is supported, and that's the entire plot. lowkey refreshing??
