2018-11-25Fix Typo: test/test_mtu.pyPaul Vinciguerra1-3/+3
first argument of a method should be named 'self'. Change-Id: Iab84a333baba9b9dfb6ffd6da66df4da331a6b11 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
2018-09-27IPIP and IPv6 fragmentationOle Troan1-3/+3
- 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.

2018-06-11MTU: Software interface / Per-protocol MTU supportOle Troan1-18/+8
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>
