iavf_alloc_rx_buffers(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, meet iavf_alloc_rx_buffers β€” the function whose whole gig is to replace used receive buffers. That's it, that's the job. We're in the Kernel API Manual, section 9, so the full glow-up name is iavf_alloc_rx_buffers(9). Slay. πŸ’…


✨ SYNOPSIS ✨

bool iavf_alloc_rx_buffers (struct iavf_ring *rx_ring , u16
cleaned_count );

πŸŽ€ ARGUMENTS πŸŽ€

  • rx_ring β€” the ring where the buffers get placed. Think of it as the receiving line at the club, but for buffers. 🫢
  • cleaned_count β€” the number of buffers to replace. Literally the count of how many used ones we're swapping out.

πŸ¦‹ DESCRIPTION πŸ¦‹

Here's the vibe check on the return value, and this part matters:

  • it returns false if all allocations were successful βœ…
  • it returns true if any of them fail 😭

so yeah, it's giving "backwards from what your brain expects" β€” false is the good outcome here. No cap.
