Subject: [PATCH bpf-next 06/20] selftests: xsk: make frame_size configurable
Date: Wed, 1 Sep 2021 12:47:18 +0200 [thread overview]
Message-ID: <20210901104732.10956-7-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20210901104732.10956-1-magnus.karlsson@gmail.com>
From: Magnus Karlsson <magnus.karlsson@intel.com>
Make the frame size configurable instead of it being hard coded to a
default. This is a property of the umem and will make it possible to
implement tests for different umem frame sizes in a later patch.
