Subject: [PATCH bpf-next 05/20] selftests: xsk: move rxqsize into xsk_socket_info
Date: Wed,  1 Sep 2021 12:47:17 +0200	[thread overview]
Message-ID: <20210901104732.10956-6-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20210901104732.10956-1-magnus.karlsson@gmail.com>

From: Magnus Karlsson <magnus.karlsson@intel.com>

Move the global variable rxqsize to struct xsk_socket_info as it
describes the size of a ring in that struct. By default, it is set to
the size dictated by libbpf.
