2017-04-06acl-plugin: make the IPv4/IPv6 non-first fragment handling in line with ACL ↵Andrew Yourtchenko1-3/+48
(VPP-682) This fixes the previously-implicit "drop all non-first fragments" behavior to be more in line with security rules: a non-first fragment is treated for the purposes of matching the ACL as a packet with the port match succeeding. This allows to change the behavior to permit the fragmented packets for the default "permit specific rules" ruleset, but also gives the flexibility to block the non-initial fragments by inserting into the begining a bogus rule which would deny the L4 traffic. Also, add a knob which allows to potentially turn this behavior off in case of a dire need (and revert to dropping all non-initial fragments), via a debug CLI.
