Subject: [PATCH bpf-next 3/6] xsk: introduce xsk_do_redirect_rx_full() helper
Date: Fri, 4 Sep 2020 15:53:28 +0200 [thread overview]
Message-ID: <20200904135332.60259-4-bjorn.topel@gmail.com> (raw)
In-Reply-To: <20200904135332.60259-1-bjorn.topel@gmail.com>
From: Björn Töpel <bjorn.topel@intel.com>
The xsk_do_redirect_rx_full() helper can be used to check if a failure
of xdp_do_redirect() was due to the AF_XDP socket had a full Rx ring.
