nfp_net_tx_ring_init(9)

💖 NAME 💖

nfp_net_tx_ring_init — bestie, this is the lil glow-up routine that fills in all the boilerplate for a TX ring ✨

Okay so picture this: you've got a TX ring and it's just sitting there, empty, no personality, no nothing. This function is the one that shows up with the iced coffee and gets it ready. It's giving "getting dressed before the party" energy 🎀

✨ SYNOPSIS ✨

void nfp_net_tx_ring_init (struct nfp_net_tx_ring *tx_ring , struct
nfp_net_dp *dp , struct nfp_net_r_vector *r_vec , unsigned int idx ,
bool is_xdp );

Yes it returns void, no it does not give you anything back, it just does the thing and dips 💅

🫶 ARGUMENTS 🫶

• tx_ring — the TX ring structure itself, aka the main character of this whole operation 👑 this is what's getting its boilerplate filled in
• dp — the NFP Net data path struct, the whole vibe of the data path fr fr
• r_vec — the IRQ vector that's servicing this ring, like the designated driver for the interrupts 🚗
• idx — the ring index, just a number, ngl very demure, very mindful
• is_xdp — a bool asking the real question: is this an XDP TX ring? 🤔 answer honestly bestie

🌈 SEE ALSO 🌈

Like, go read these too, they're all lowkey iconic in their own way:

• Kernel file ./drivers/net/ethernet/netronome/nfp/nfp_net_dp.c — yes that's the real path, no I'm not making it up 🦋
• nfp_net_rx_alloc_one(9)
• nfp_net_rx_ring_init(9)
• nfp_net_rx_ring_reset(9)
• nfp_net_rx_ring_bufs_free(9)
• nfp_net_rx_ring_bufs_alloc(9)
• nfp_net_rx_ring_free(9)
• nfp_net_rx_ring_alloc(9)

Look at all those RX friends — this is the TX side but the whole fam is linked up, iykyk 💜

Ok that's the whole page bestie, no cap, nothing hidden, every single arg and cross-reference accounted for 💀 now go init some rings 🧚
