Hi all,

I forgot to tell you I work on Linux Debian 8.
I set .rss_hf value  to 0x7ef8 and now I see packets but:

I get an error message: *i40e_dev_alarm_handler(): ICR0: HMC error*
I found here https://mails.dpdk.org/archives/dev/2018-September/111338.html
that I am in the following case:
+ if (icr0 & I40E_PFINT_ICR0_HMC_ERR_MASK)
+ PMD_DRV_LOG(ERR, "ICR0: HMC error");
Does anyone know what goes wrong ?

Additionally, I get many RX errors:

Port  RX pkt    RX byte    TX pkt    TX byte  RX error   TX error
 1      3290      5196839         0          0           62001          0
Queue  RX pkt    RX byte    TX pkt    TX byte  RX error   TX error
 0              0               0             0            0
0            0
 1              0               0             0            0
0            0

Thank you for your help,

Ikuzar
