Subject: [RFC v2 PATCH 0/5] seg6: Segment routing fixes

This patch set includes fixes to bring the segment routing
implementation into conformance with the latest version of the
draft (draft-ietf-6man-segment-routing-header-19). Also, segment
routing receive function calls ip6_parse to properly parse TLVs
in parsing loop.

Changes include:

  - Update TLV macro definitions. Mark obsoleted TLVs as such, add
    definitions for PAD1 and PADN
  - Mark obsoleted flags as such
  - Implement parsing loop in sr_has_hmac to find HMAC TLV without
    relying on obsoleted flag
  - Parameterize ip6_parse_tlv so that it can be used for parsing
    segment routing TLVs
  - Add sysctls for segment routing TLV parsing limits
  - Segment routing receive functions call ip6_parse_tlv

Tom Herbert (5):
  seg6: Fix TLV definitions
  seg6: Obsolete unused SRH flags
  ipv6: Paramterize TLV parsing
  seg6: Add sysctl limits for segment routing header
  seg6: Leverage ip6_parse_tlv
