💅 efx_nic_copy_stats — bestie's guide to the kernel API manual ✨

okay so real talk, this is the manual page for efx_nic_copy_stats(9), and yes it's a kernel API manual page, we're fancy now 🎀

🌸 NAME 🌸

efx_nic_copy_stats — copy stats from the DMA buffer in to an intermediate buffer. This is used to get a consistent set of stats while the DMA buffer can be written at any time by the NIC.

fr fr, that's the whole point: the NIC can be out here scribbling on the DMA buffer literally whenever, so you grab a copy and work off that instead 💖

✨ SYNOPSIS ✨

int efx_nic_copy_stats (struct efx_nic *efx , __le64 *dest );

---

🦋 ARGUMENTS 🦋

• efx — the associated NIC. that's your main character struct, the one doing the network stuff 😌
• dest — destination buffer. Must be the same size as the DMA buffer. like, non-negotiable, no cap 🙈
