💅 i40e_dcbnl_get_pg_tc_cfg_rx(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes, this is that i40e_dcbnl_get_pg_tc_cfg_rx(9) page, the one you were looking for. pull up a chair, we're getting into CEE PG Rx config and honestly? it's giving niche-but-iconic. 🦋

✨ NAME ✨

i40e_dcbnl_get_pg_tc_cfg_rx — Get CEE PG Rx config. that's the whole vibe. 🌸

🎀 SYNOPSIS 🎀

void i40e_dcbnl_get_pg_tc_cfg_rx (struct net_device *netdev , int prio ,
u8 *prio_type , u8 *pgid , u8 *bw_pct , u8 *up_map );

yep, that's a void function, no return value to obsess over. it just hands you stuff through the pointers. slay. 💅

🫶 ARGUMENTS 🫶

  • netdev — the corresponding netdev. like, the network device in question, bestie. that's the one. 🧚
  • prio — the corresponding user priority. an int, right there in the middle of the signature.
  • prio_type — the traffic priority type. u8 *, so it's a pointer, and you're getting the type out of it.
  • pgid — the PG ID. yes, the Priority Group ID, no cap. 👑
  • bw_pct — the BW percentage for the corresponding BWG. bandwidth percentage, for the BWG. iykyk.
  • up_map — prio mapped to corresponding TC. so the user priority → traffic class mapping, lowkey the whole point.

💖 DESCRIPTION 💖

Get Rx PG settings for CEE mode, periodt. ✨

here's the cute part: the UP2TC map is applied in the same manner for Tx and Rx — it's symmetrical, bestie, like matching outfits — so this function just returns the TC information for the given priority accordingly. it's giving "one map, two directions, mutual main character energy." 🌈

ngl this one is a getter, so it's filling in the values your pointers point at. no surprises, no drama. 💀
