背景:
意外送来一张 Marvell FastLinQ 41000 Series的网卡,
驱动是 QEDE.
需要测试 40Gbit 速率下的 收包表现.
猫腻:
MoonGen 附带的DPDK, 编译完成后,
testpmd是可以探测出 QEDE 网卡.
MoonGen 启动就无法 探测出 QEDE 驱动.

在DPDK_LIBS中添加 rte_pmd_qede
SET(DPDK_LIBS
rte_net rte_ethdev rte_distributor rte_mbuf rte_pmd_bond rte_kni rte_pmd_ring rte_power
rte_acl rte_eal rte_kvargs rte_mempool rte_mempool_ring rte_pmd_e1000 rte_pmd_virtio rte_ring
rte_cfgfile rte_hash rte_lpm rte_meter rte_pmd_i40e rte_pmd_vmxnet3_uio rte_sched rte_timer

rte_pmd_ena rte_pmd_nfp rte_stack rte_bus_vdev rte_bus_pci rte_pci rte_cryptodev
)
改好之后:
SET(DPDK_LIBS
rte_net rte_ethdev rte_distributor rte_mbuf rte_pmd_bond rte_kni rte_pmd_ring rte_power
rte_acl rte_eal rte_kvargs rte_mempool rte_mempool_ring rte_pmd_e1000 rte_pmd_virtio rte_ring
