9============================================
10
11seg6_enabled - BOOL
12 Accept or drop SR-enabled IPv6 packets on this interface.
13
14 Relevant packets are those with SRH present and DA = local.
15
16 * 0 - disabled (default)
17 * not 0 - enabled
18
19seg6_require_hmac - INTEGER
20 Define HMAC policy for ingress SR-enabled packets on this interface.
21
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
25
26 Default is 0.

36 -1 set flowlabel to zero.
37 0 copy flowlabel from Inner packet in case of Inner IPv6
38 (Set flowlabel to 0 in case IPv4/L2)
