- seg6_enabled - BOOL
- Accept or drop SR-enabled IPv6 packets on this interface. - Relevant packets are those with SRH present and DA = local. - 0 - disabled (default) 
- not 0 - enabled 
 
- seg6_require_hmac - INTEGER
- Define HMAC policy for ingress SR-enabled packets on this interface. - -1 - Ignore HMAC field 
- 0 - Accept SR packets without HMAC, validate SR packets with HMAC 
- 1 - Drop SR packets without HMAC, validate SR packets with HMAC 
 - Default is 0. 
- seg6_flowlabel - INTEGER
- Controls the behaviour of computing the flowlabel of outer IPv6 header in case of SR T.encaps - -1 - set flowlabel to zero. - 0 - copy flowlabel from Inner packet in case of Inner IPv6 (Set flowlabel to 0 in case IPv4/L2) - 1 - Compute the flowlabel using seg6_make_flowlabel() - Default is 0.
