Thanks for the feedback Nick.

For reference, the build issues on el7.4 were easy enough to fix, so I 
have fixed those and rebuilt the package against the RHEL 7.4 kernel and 
released it to our testing repository here:

kmod-via-rhine-1.5.1-3.el7_4.elrepo.x86_64.rpm

I note the newly built package is only compatible with 7.4 series 
kernels and is not backward compatible with earlier kernels.

For reference, the fix is:

-	dev->trans_start = jiffies; /* prevent tx timeout */
+	netif_trans_update(dev); /* prevent tx timeout */

This was a treewide patch applied upstream in 2016, and presumably 
backported to the RHEL7.4 kernel, so potentially affects a number of 
elrepo drivers using trans_start updates.

If your user has any issues with the driver, I would apply the above fix 
and rebuild against your 7.4 kernel.
