💅 nfp_flower_del_offload(9) — the "bye bye flow" page 🦋

okay so this is a page from the Kernel API Manual and honestly? it's a little baddie. it's giving "cleanup era" and we're obsessed. no cap, this one is short but it does exactly what it says on the tin 💖

✨ NAME ✨

nfp_flower_del_offload — bestie, this one removes a flow from hardware. that's it, that's the vibe 🎀

🌸 SYNOPSIS 🌸

int nfp_flower_del_offload (struct nfp_app *app , struct net_device
*netdev , struct flow_cls_offload *flow );

like, look at that signature. three args, returns an int. we love a simple queen 👑

🦋 ARGUMENTS 🦋

• app — pointer to the APP handle. your app bestie, the lil entry point into everything.
• netdev — the netdev structure. yeah, that one 🫶
• flow — the TC flower classifier offload structure. this is the flow we're about to send to the shadow realm 💀

🔥 DESCRIPTION 🔥

okay so the way this works: it removes a flow from the repeated hash structure and clears the action payload. and here's the part that lowkey matters — any flows merged from this are also deleted. so like, it's not just deleting one thing, it's deleting the whole lil friend group that got merged in. main character energy but make it a cascade 😭

ngl that's the whole description. short, sweet, slays, periodt ✨

🌈 RETURN 🌈

• a negative value on error 🙈 (something went wrong, rip)
• 0 if removed successfully 👑 (we ate, we left no crumbs)

💜 SEE ALSO 💜

• Kernel file ./drivers/net/ethernet/netronome/nfp/flower/offload.c — the source, the mothership, the place to go if you want the real lore 🧚
• nfp_flower_merge_offloaded_flows(9) — the merge bestie
• nfp_flower_validate_pre_tun_rule(9) — the validation bestie

lowkey reminder: this is a deletion function, so like... it's gonna delete stuff. if you merged flows, they're going with it. no takebacksies, iykyk 💅
