Re: [dpdk-users] TestPMD testing with VMX3NET Devices...

[Jamie Fargen <jfargen@redhat.com>]

Rami-

Attached is the results of running testpmd with loglevel=8.

The setting CONFIG_RTE_LIBRTE_VMXNET3_PMD=y seems to be set.
# grep 'CONFIG_RTE_LIBRTE_VMXNET3_PMD=y' build/.config
CONFIG_RTE_LIBRTE_VMXNET3_PMD=y

Should a library be build like
/usr/lib64/dpdk-pmds/librte_pmd_vmxnet3.so.1?  If so I don't see it.
# find /usr/lib64/dpdk-pmds
/usr/lib64/dpdk-pmds
/usr/lib64/dpdk-pmds/librte_pmd_bnxt.so.2
/usr/lib64/dpdk-pmds/librte_pmd_e1000.so.1
/usr/lib64/dpdk-pmds/librte_pmd_enic.so.1
/usr/lib64/dpdk-pmds/librte_pmd_failsafe.so.1
/usr/lib64/dpdk-pmds/librte_pmd_i40e.so.2
/usr/lib64/dpdk-pmds/librte_pmd_ixgbe.so.2
/usr/lib64/dpdk-pmds/librte_pmd_mlx4.so.1
/usr/lib64/dpdk-pmds/librte_pmd_mlx5.so.1
/usr/lib64/dpdk-pmds/librte_pmd_nfp.so.1
/usr/lib64/dpdk-pmds/librte_pmd_qede.so.1
/usr/lib64/dpdk-pmds/librte_pmd_ring.so.2
/usr/lib64/dpdk-pmds/librte_pmd_softnic.so.1
/usr/lib64/dpdk-pmds/librte_pmd_vhost.so.2
/usr/lib64/dpdk-pmds/librte_pmd_virtio.so.1
