From 80034cacde8f9c4d7cd4ae73316eeec6cc2fd67a Mon Sep 17 00:00:00 2001

Date: Thu, 10 Mar 2022 12:03:13 +0100
Subject: [PATCH 2/3] Set the number of written bytes for used descs
As the Linux driver ignores the "len" field of used descriptors, we
didn't bother to set it properly when return those descriptors to the
queue.
The problem is that other implementations (at least, the Windows one),
do care about it, so let's do the right thing and set it properly.

From: Sebastian Hasler <sebastian.hasler@stuvus.uni-stuttgart.de>
Date: Wed, 2 Feb 2022 17:50:34 +0100
Subject: [PATCH 1/3] process_queue_pool: Only acquire the VringMutex lock once
Previously, the worker task in `process_queue_pool()` called
up to 3 functions on `worker_vring` where each function is a
wrapper that first locks the mutex. This is unneccessary
congestion. We fix this by locking the mutex once.
