IPIP and IPv6 fragmentation
- Error where ICMPv6 error code doesn't reset VLIB_TX = -1 Leading to crash for ICMP generated on tunnelled packets - Missed setting VNET_BUFFER_F_LOCALLY_ORIGINATED, so IP in IPv6 packets never got fragmented. - Add support for fragmentation of buffer chains. - Remove support for inner fragmentation in frag code itself.
