Overview

Long ago I ran into the below 2 situations that required the below 2 commits.
I do not have access to pcaps for these.
Unit tests are added for some code coverage.
Figured I share the changes in case it helps you or anyone else. Thanks!

Changes:

  1. IPv6 packets that hade the Authentication Extension header without padding
  2. Added support for the case where the end of IP options extends past the last byte of the End Of Options option
