Re: [dpdk-users] Unable to recognize master/representor on the multiple IB devices
Hi Sankalpa, Have you enabled SRIOV and switchdev mode correctly? Is there any error in demsg? Here is the regular steps: 1. enable sriov - new VF ports shown in `ip link` 2. unbind VFs - new VF ports disappear 3. enable switchdev mode - new representor ports shown in `ip link` 4. bind VFs again or passthrough to VM Best Regards, Xueming > -Original Message- > From: users On Behalf Of Sankalpa Timilsina > Sent: Sunday, May 23, 2021 2:43 AM > To: users@dpdk.org > Subject: [dpdk-users] Unable to recognize master/representor on the multiple > IB devices > > Hi, I am getting a DPDK MLX5 probing issue. > >1.

Hello Sankalpa, Are you seeing this with testpmd? If so can you provide the command line? If not, can you provide the EAL parameters and the devargs used?
