Hi, Hanoch
If DPDK PF, the commit affects that because it introduces an argument (itr_idx)
for i40e_vsi_ena
Hi, Hanoh
Yes, that's true.
Thanks

Hi Jingjing,
1. The issue is with DPDK PF.
2. The rate is high ~10gb, one DP core, one latency core.
3. The fix is here
/* Bind all RX queues to
patch and fix this latency issue in the different way?
Thanks,
Hanoh

Hi All,
While integrating dpdk17.11 into TRex
Hi All,
While integrating dpdk17.11 into TRex latest code a new latency issue is
observed (i40e is very sensitive because it has very good resolution due to
Qos configuration).
git bitsec found the following commit.
With this commit we observe high spikes of Rx latency (~40usec) vs (~8usec).
