[dpdk-dev] Mellanox 100GbE MCX516A-CCAT

[Yasuhiro Ohara]

Thank you for the suggestion, Olga.

I was in a confusion, but now somehow I get the card to work,
so for the record I share my current status here.

I was confused about my ConnectX-5 type, which was MCX556A-ECAT
rather than MCX516A-CCAT. Currently the card seems to be working
fine with the below configuration.

MCX556A-ECAT ConnectX-5
MCX556A-ECAT ConnectX-5 Mellanox NIC firmware version: 16.22.1002(?)
Mellanox OFED driver version: MLNX_OFED_LINUX-4.2-1.2.0.0 (--upstream-libs)
DPDK version: 17.11.0 (dpdk-17.11.tar.xz)

Below matrix should be important (which I haven't been following yet):
<http://www.mellanox.com/page/mlnx_ofed_matrix?mtag=linux_sw_drivers>

Although I didn't record it properly (because I didn't thought it's
relevant), sometimes /var/tmp is not writable in my test environment.
And I'm guessing that it might have been the source of the problem,
making the ConnectX-5 from functioning.

There's still many unsure things in me, and I will investigate more
and will continue to report in the Mellanox Community.

Thanks.

regards,
Yasu
