ice_set_q_coalesce(9)

💅 ice_set_q_coalesce(9) — the kernel API manual, but make it make sense

okay so bestie, you're in the ice driver docs (that's the Kernel API Manual, mmmkay) and today's main character is ice_set_q_coalesce. it does exactly one iconic thing: it sets a queue's ITR/INTRL (coalesce) settings. that's it. that's the whole vibe. ✨

---

🎀 SYNOPSIS 🎀

int ice_set_q_coalesce (struct ice_vsi *vsi , struct ethtool_coalesce
*ec , int q_num );

literally just three args and an int return, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• vsi — the struct ice_vsi * that's associated with the queue you're updating. like, which VSI owns this queue, bestie.
• ec — the coalesce settings you want the device to be programmed with. this is the struct ethtool_coalesce * carrying the values.
• q_num — the queue number/index whose ITR/INTRL (coalesce) settings you're updating. yes it's an int. yes it's the one you pick.

---

🔥 DESCRIPTION 🔥

ngl the description is short and sweet: it returns 0 on success, and a negative value under these conditions:

1. setting the Tx or Rx ITR/INTRL (coalesce) settings failed. 💀
2. the q_num you passed in is not a valid number/index for the Tx and Rx rings. 🙈

so if you get a negative back, it's one of those two. that's the whole mood. no extra lore, don't @ me.
