2018-09-27IPIP and IPv6 fragmentationOle Troan1-0/+12
- 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.

- many of the patches fd.io applies in test/patches/2.3.3 are now upstreamed in 2.4 - 2.4 adds support for IGMPv3 which is my main motivation for the upgrade Change-Id: If2c0a524e3cba320b4a5d8cd07817c6ea2bf0c5a Signed-off-by: Neale Ranns <nranns@cisco.com>
2018-03-01Fix ERSPAN encap to set EN bits in the header and add test caseJohn Lo1-1/+29
For ERSPAN encap, both bits in the EN field of the header should be set to indicate any VLAN tag in the original Ethernet frame is preserved. Added SPAN L2 test case where the mirrored packet output is a GRE ERSPAN tunnel. Change-Id: Ie7a40992a9278469c24aa6fa9e122b4505797d10 Signed-off-by: John Lo <loj@cisco.com>

2017-12-09BIER in non-MPLS netowrksNeale Ranns1-3/+17
as decsribed in section 2.2 ihttps://tools.ietf.org/html/draft-ietf-bier-mpls-encapsulation-10 with BIFT encoding from: https://tools.ietf.org/html/draft-wijnandsxu-bier-non-mpls-bift-encoding-00 changes: 1 - introduce the new BIFT lookup table. BIER tables that have an associated MPLS label are added to the MPLS-FIB. Those that don't are added to the BIER table 2 - BIER routes that have no associated output MPLS label will add a BIFT label. 3 - The BIER FMask has a path-list as a member to resolve via any possible path.

2017-10-06Initial GENEVE TUNNEL implementation and tests.Marco Varlese2-0/+69
Notes on this first implementation: * First version of the implementation does NOT support GENEVE OPTIONS HEADER: it isn't well understood what the purpose of the OPTIONS will be and/or what content would be placed in the variable option data; Once the IETF work will evolve and further information will be available it could be possible to modify the frame rewrite to contemplate the actual GENEVE OPTIONS.
