Hi, I am trying to run vpp 19.04 with Mellanox(ConnectX-4) NIC and have the following queries:-
I followed the below mentioned steps to compile vpp 19.04 by enabling Mellanox support 1) Export the following env variabled a) export CONFIG_RTE_LIBRTE_MLX5_PMD=y b) export DPDK_MLX5_PMD=y c) export PLATFORM=vpp 2) Modified the dpdk.mk(path:third-party/vpp/vpp_1904/build/external/packages/dpdk.mk) file to set "DPDK_MLX5_PMD=y" to enable Mellanox support. 3) Also, i copied "librte_pmd_mlx5_glue.so.19.02.0" explicitly before running vpp. Query 1:- When i brought the vpp up, the Mellanox interfaces were not detected by vpp. Executed "show interfaces" CLI but couldn't see any Mellanox interface. Please let me know whether the steps followed are correct/or missing any steps. Query 2:- Also, I came across the following link on the internet https://lists.fd.io/g/vpp-dev/message/12979 The link talks about the new native driver(RDMA ethernet driver) and creation of a new rdma virtual interface that would bind to Linux netdev of the physical port to be used. By following the steps mentioned in https://gerrit.fd.io/r/#/c/19364/3/src/plugins/rdma/rdma_doc.md, i was able to create an interface at vpp level and assign an ip to that interface. I verified the same by executing "show interfaces" CLI and interfaces were being shown this time. Can anyone comment whether it is the correct way of testing Mellanox NIC with vpp 19.04?
