Series | gre: add sequence number for collect md mode. | expand |
From: William Tu <u9012063@gmail.com> Date: Thu, 1 Mar 2018 13:49:56 -0800 > Currently GRE sequence number can only be used in native tunnel mode. > The first patch adds sequence number support for gre collect > metadata mode, and the second patch tests it using BPF. > > RFC2890 defines GRE sequence number to be specific to the traffic > flow identified by the key. However, this patch does not implement > per-key seqno. The sequence number is shared in the same tunnel > device. That is, different tunnel keys using the same collect_md > tunnel share single sequence number. > > A new BFP uapi tunnel flag 'BPF_F_SEQ_NUMBER' is added. > -- > v1->v2: > rename BPF_F_GRE_SEQ to BPF_F_SEQ_NUMBER suggested by Daniel Series applied, thank you.
