[ovs-discuss] Linux 3.0 Support

[Justin Pettit]

I'm guessing because they're going to remove the "hh" member from the "dst_entry" struct in Linux 3.1.  ;-)  I imagine shortly after 3.1 is released, we'll make the version in git work with it.  In the meantime, you're better off using Linux 3.0 unless you want to modify the OVS source yourself.  If you don't care about tunneling, you may be able to just comment out the offending lines, but of course you may run into other problems.

Good luck!
