0011 seg6_enabled - BOOL
0012 Accept or drop SR-enabled IPv6 packets on this interface.

0014 Relevant packets are those with SRH present and DA = local.
0015
0016 * 0 - disabled (default)
0017 * not 0 - enabled
0018
0019 seg6_require_hmac - INTEGER
0020 Define HMAC policy for ingress SR-enabled packets on this interface.
0021
0022 * -1 - Ignore HMAC field
0023 * 0 - Accept SR packets without HMAC, validate SR packets with HMAC
0024 * 1 - Drop SR packets without HMAC, validate SR packets with HMAC
0025

0027
0028 seg6_flowlabel - INTEGER
0029 Controls the behaviour of computing the flowlabel of outer

0032 == =======================================================
0033 -1 set flowlabel to zero.
0034 0 copy flowlabel from Inner packet in case of Inner IPv6
0035 (Set flowlabel to 0 in case IPv4/L2)
