[dpdk-users] Building mlx4 drivers
msowka at gmail.com
Wed Nov 8 15:27:41 CET 2017
I'm working off master, couple commits after 17.11-rc2 tag. As I'm in early
development myself I haven't nailed down to a release yet. I figured the
docs aren't completely updated, and that's why I then ended up installing
I was previously installing with `./mlnxofedinstall --guest`. I assume the
`./mlnxofedinstall --dpdk --upstream-libs` as instructed installs the
rdma-core and upstream libs, ? Should I also include the --guest argument,
as I'm in a HyperV environment, ?
Thank You Both.
Building wihtout a glitch now,
