Subject: [PATCH net-next 0/3] net: gro: reduce extension header parsing overhead
Date: Thu, 21 Dec 2023 19:44:13 +0100	[thread overview]
Message-ID: <f4eff69d-3917-4c42-8c6b-d09597ac4437@gmail.com> (raw)

This series attempts to reduce parsing overhead of IPv6 extension headers
in GRO and GSO, by removing extension header specific code and enabling
the frag0 fast path.
 
The following changes were made:
- Specific unnecessary HBH conditionals were removed by adding HBH offload
  to inet6_offloads
- Added a utility function to support frag0 fast path in ipv6_gro_receive
- Added self-test for IPv6 packets with extension headers in GRO
