The patch is broken for me.

patching file lib/netdev-dpdk.c
patch: **** malformed patch at line 28: ROUND_DOWN_POW2(MAX_NB_MBUF/MIN_NB_MBUF))

or

$ git am /tmp/foo.mbox
Applying: netdev-dpdk: Increase limit for dpdk ring names
fatal: corrupt patch at line 6
Patch failed at 0001 netdev-dpdk: Increase limit for dpdk ring names
The copy of the patch that failed is found in:
   /home/fleitner/repo/ovs/master/.git/rebase-apply/patch


Otherwise it looks correct to me.
