hi, I rpmbuild the ovs-dpdk by myself, and the "config/common_base" : CONFIG_RTE_LIBRTE_BNX2X_PMD=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG_INIT=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG_RX=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG_TX=y CONFIG_RTE_LIBRTE_BNX2X_MF_SUPPORT=y CONFIG_RTE_LIBRTE_BNX2X_DEBUG_PERIODIC=y
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|16773337|dpdk|INFO|EAL: probe driver: 14e4:168e net_bnx2x 2017-11-09T09:28:30.038Z|16773338|dpdk|WARN|EAL: Requested device 0000:20:00.1 cannot be used 2017-11-09T09:28:30.038Z|16773339|dpdk|ERR|EAL: Driver cannot attach the device (0000:20:00.1) 2017-11-09T09:28:30.038Z|16773340|netdev_dpdk|WARN|Error attaching device '0000:20:00.1' to DPDK 2017-11-09T09:28:30.038Z|16773341|netdev|WARN|dpdk-eth2: could not set configuration (Invalid argument) And, my NIC firmware is : [root@node-4 ~]# ethtool -i eth2 driver: bnx2x version: 1.712.30-0 firmware-version: bc 7.0.49 expansion-rom-version: bus-info: 0000:20:00.1 supports-statistics: yes supports-test: yes supports-eeprom-access: yes supports-register-dump: yes supports-priv-flags: yes Does the fm version not satisfies ? or some other reasons ?
