PS1: Several comments: * Do we really want to have this configurable over envvar? what's the reasoning? to be able to temporarily spot failures and compare? * It probably makes sense to change the patch to do the following, to avoid calling io_uring_submit() every loop iteration unconditionally: * in rubmit_rx, submit_tx, etc, if we had to call io_uring_submit() then set some new global var "io_uring_submit_needed" to true. * during the poll loop iteration, only call io_uring_submit() if the var was set to true, and set it to false again.
