Re: [dpdk-dev] [dpdk-stable] 18.11.3 (LTS) patches review and test

Hi,

Replaying here because I can't find the first email in the thread.

Regarding testing results with Mellanox devices, we did basic functional testing with testpmd, and don't see any issues.

Testing matrix:
- NIC: ConnectX-5 / OS: RHEL 7.4 / Kernel: 5.3.0 / Driver: rdma-core v25.1 / fw: 16.26.1040
- NIC: ConnectX-4 Lx / OS: RHEL 7.4 / Kernel: 5.3.0 / Driver: rdma-core v25.1 / fw: 14.26.1040
- NIC: ConnectX-5 / OS: RHEL 7.4 / Kernel: 3.10.0-693.el7.x86_64 / Driver: MLNX_OFED_LINUX-4.7-1.0.0.1 / fw: 16.26.1040
- NIC: ConnectX-4 Lx / OS: RHEL 7.4 / Kernel: 3.10.0-693.el7.x86_64 / Driver: MLNX_OFED_LINUX-4.7-1.0.0.1 / fw: 14.26.1040

I apologize for the delay in reporting our results.

Thanks,
Ali
