I rpmbuild the ovs-dpdk by myself, and the "config/common_base" :
then ,I build the rpm of dpdk/dpdk-devel，and installed the 2 rpms to rpmbuild the ovs-dpdk。
when I used the ovs-dpdk with the bcm-NIC, there comes the error：
here is the error in "/var/log/openvswitch/ovs-vswitchd.log"
2017-11-09T09:28:30.038Z|16773336|dpdk|INFO|EAL: PCI device 0000:20:00.1 on NUMA socket 0

2017-11-09T09:28:30.038Z|16773341|netdev|WARN|dpdk-eth2: could not set configuration (Invalid argument)
And, my NIC firmware is :
[root at node-4 ~]# ethtool -i eth2
firmware-version: bc 7.0.49
Does the fm version not satisfies ? or some other reasons ?
