i40e_clean_tx_irq(9)

💖 i40e_clean_tx_irq 💖

okay so bestie, welcome to another page of the Kernel API Manual — yes we're back in the i40e trenches, but this one is actually kind of a big deal 🫶

✨ NAME ✨

i40e_clean_tx_irq — reclaim resources after transmit completes 💅

✨ SYNOPSIS ✨

bool i40e_clean_tx_irq (struct i40e_vsi *vsi , struct i40e_ring *tx_ring
, int napi_budget , unsigned int *tx_cleaned );

✨ ARGUMENTS ✨

• vsi — the VSI we care about 🎀 like, the specific one, okay? that's the whole vibe check.
• tx_ring — the Tx ring we're cleaning up. tidy tidy ✨
• napi_budget — used to figure out whether we're in netpoll. iykyk 👀
• tx_cleaned — an Out parameter, set to the number of TXes cleaned. so you hand it over and it comes back with a receipt 💀

✨ DESCRIPTION ✨

Returns true if there's any budget left (e.g. the clean is finished) ✅

like, that's the whole thing. it returns a bool, and true means budget remains — the clean is done-done. no cap, that's it 🌈
