[dpdk-dev] [PATCH v2 1/3] app/testpmd: add MPLSoUDP encapsulation

Ori Kam orika at mellanox.com
Sun Oct 7 16:41:52 CEST 2018


MPLSoUDP is an example for L3 tunnel encapsulation.

Due to the complex encapsulation of MPLSoUDP flow action and based on the
fact testpmd does not allocate memory, this patch adds a new command in
testpmd to initialise a global structure containing the necessary
information to make the outer layer of the packet.  This same global
structure will then be used by the flow command line in testpmd when the
action mplsoudp_encap will be parsed, at this point, the conversion into
such action becomes trivial.

This global structure is only used for the encap action.
