12 Accept or drop SR-enabled IPv6 packets on this interface.
14 Relevant packets are those with SRH present and DA = local.
16 * 0 - disabled (default)
19 seg6_require_hmac - INTEGER
20 Define HMAC policy for ingress SR-enabled packets on this interface.
22 * -1 - Ignore HMAC field
23 * 0 - Accept SR packets without HMAC, validate SR packets with HMAC
24 * 1 - Drop SR packets without HMAC, validate SR packets with HMAC
28 seg6_flowlabel - INTEGER
29 Controls the behaviour of computing the flowlabel of outer
30 IPv6 header in case of SR T.encaps
32 == =======================================================
33 -1 set flowlabel to zero.
34 0 copy flowlabel from Inner packet in case of Inner IPv6
35 (Set flowlabel to 0 in case IPv4/L2)
