Hi there,

I've been struggling to get two systems with X710-DA2s communicating properly.

When I begin copying files over the network via NFS for simple benchmarking I 
get this:

[250501.852843] i40e 0000:41:00.0 p1p1: NIC Link is Up 10 Gbps Full Duplex,

When I try using the NVMUpdatePackage to update the firmware to try and correct 
this issue it says:

[root@cf Linux_x64]# ./nvmupdate64e -u -l -o update.xml -c nvmupdate.cfg

I've tried with both i40e 1.0.11-k (built into RHEL 7.1) and 1.2.38 (latest 
from intel)

Can anyone help me to get basic functionality on these NICs?
