Subject: [PATCH net-next v2 0/2] ipv6: sr: Simplify and optimize HMAC calculations

This series simplifies and optimizes the HMAC calculations in
IPv6 Segment Routing.

Changed in v2:
- Rebased on top of latest net-next.  Dropped "ipv6: sr: Fix MAC
  comparison to be constant-time" since it was upstreamed already.
  Moved key preparation to seg6_hmac_info_add().

Eric Biggers (2):
  ipv6: sr: Use HMAC-SHA1 and HMAC-SHA256 library functions
  ipv6: sr: Prepare HMAC key ahead of time
