The patchset introuduces IPv6 optimized MFEX profiles
with AVX512 which can deliver upto 20% to 30% gain in
performance over the existing scalar data-path.

Hashing Optimization are also included which can further
improve performance by approximately 10%.

The patch also removes the magic numbers for MF bits, packet offsets
and packet lenghts.

---
v7:
- Remove magic numbers from AVX512 Profiles.
v5:
- Add Ipv6 and TCP packet length checks.
v4:
- rebase to master.
- use static key lenghts for different packet types.
v3:
- rebase to master.
v2:
- fix the CI build.
- fix check-patch for co-author.
