Extracting the call to ipv6_hdrlen_offset from lb6_extract_tuple allows for optimizations based on squashing ipv6_hdrlen and ipv6_get_fraginfo. Do the parallel change to lb4_extract_tuple. Signed-off-by: Maxim Mikityanskiy <maxim@isovalent.com>
Both functions go over the IPv6 extension headers. To reduce verifier complexity and CPU cycles, go over them once where easily possible (where both functions are called together). Signed-off-by: Maxim Mikityanskiy <maxim@isovalent.com>
