    Cannot control XL710 VF interrupte rate

    fishingbear2


      Hi,

       

      I'm doing the tuning job for XL710 VF on a FreeBSD10 VM (driver is ixlv-1.2.11) hosted on a kvm-hypervisor server (pf driver is i40e-1.4.25).

      I found for each queue of the vf the interrupte rate is very high (>10000/sec).

      As said in the datasheet, I tried to set I40E_VF_ITRN by the VF driver and set I40E_VPINT_RATEN by the PF driver. But this didn't work.

      I have upgraded the NVM to 5.02 the latest version.

       

      Could anybody help me resolve the issue?
