From 6f02527729bd31ca4e473bff19fda4ccd5889148 Mon Sep 17 00:00:00 2001 From: Norman Maurer Date: Mon, 28 Jul 2025 20:59:53 -1000 Subject: io_uring/net: Allow to do vectorized send At the moment you have to use sendmsg for vectorized send. While this works it's suboptimal as it also means you need to allocate a struct msghdr that needs to be kept alive until a submission happens. We can remove this limitation by just allowing to use send directly.
