- ====================
- /proc/sys/net/conf/<iface>/seg6_* variables:
- ============================================
- 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.
- /proc/sys/net/ipv6/seg6_* variables:
- ====================================
- 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.
