Subject: [PATCH bpf-next v3 10/11] mlx5: Support RX XDP metadata
Date: Tue, 29 Nov 2022 11:34:51 -0800 [thread overview]
Message-ID: <20221129193452.3448944-11-sdf@google.com> (raw)
In-Reply-To: <20221129193452.3448944-1-sdf@google.com>
From: Toke Høiland-Jørgensen <toke@redhat.com>
Support RX hash and timestamp metadata kfuncs. We need to pass in the cqe
pointer to the mlx5e_skb_from* functions so it can be retrieved from the
XDP ctx to do this.
