Subject: [PATCH bpf-next 2/9] bpf: add csum_diff helper to xdp as well
Date: Sat, 20 Jan 2018 01:24:30 +0100 [thread overview]
Message-ID: <20180120002437.3528-3-daniel@iogearbox.net> (raw)
In-Reply-To: <20180120002437.3528-1-daniel@iogearbox.net>
Useful for porting cls_bpf programs w/o increasing program
complexity limits much at the same time, so add the helper
to XDP as well.
