Some more info that may/may not be useful:- Out of interest I removed the "zc:" from the device name, and immediately got the "Wrong ring version". A quick google revealed a thread from your good self, and of course I had been hopping between 7.0.0 and 7.4.0 for fault-finding. The 'rmmod' command was refusing to unload the pf_ring.ko module because of an unnamed dependency, and it looks like a 7.0.0 kernel module was being called from our 7.4.0 application.
A quick reboot of the box and re-load of the correct 7.4.0 drivers has resolved that issue, and we can now write to the network via the "eth0" device. Using "zc:eth0" now produces a different error message - "socket type not supported". A.
