Description of problem:
Performance is very low when using e810 nic in a ovs-dpdk scenario. This happen in both ml2-ovs and ovn

Test conditions:

       PF ----------------- ovs bridge e810 -------  
TREX                                                Testpmd
       PF ----------------- ovs bridge e810 -------

Using 1 pmd core, 1 flow

x710         ---> 2.8 mpps
e810 in 16.2 ---> 2.5 mpps
e810 in 17.1 ---> 2.1 mpps .. 16% less than in 16.2, 25% less than x710

Some time ago i already opened this bug but at that point the performance was only 0.5 mpps. After solving that issues we get 2.1 mpps, which is still low
