[dpdk-users] DPDK mlx4 PMD on Azure VM

In case anyone else might need.

I solved this issue by installing the mlx4 related libraries from mlxn
ofed source for azure.

1) download source from:


Note: download the sources (48M), not the others. For some reason,
only the source package works for me.

2) unpack and install
./install.pl --guest --dpdk --upstream-libs

3) after installation completes, run
/etc/init.d/openibd restart

this will insert mlx4 related module into kernels.

After that, build dpdk and run testpmd seems working for me

So not sure what is the deal with the MLNX packages for Azure, but
this seems to be way for me to make it work.

Hope this may help someone else.
