firmware of Intel X710-DA2 (in Dell PowerEdge R330) :

- "fw 5.0.40043 api 1.5 nvm 5.05 0x80002899 17.5.11" : no internet access possible

- "fw 6.80.48812 api 1.7 nvm 6.00 0x80003751 18.5.17" : Internet access possible with many errors

only some servers are affected by this problem. I found a difference:

The problem-free machines have a line:
[ 2.522869] i40e 0000:02:00.0: Features: PF-id[0] VFs: 64 VSIs: 66 QP: 8 RSS FD_ATR FD_SB NTUPLE DCB VxLAN Geneve PTP VEPA

Those with errors have a line:
[ 2.932705] i40e 0000:01:00.0: Features: PF-id[0] VFs: 64 VSIs: 66 QP: 16 RSS FD_ATR FD_SB NTUPLE DCB VxLAN Geneve PTP VEPA

QP (num_queue_pairs) = 8 => ok all is ok with Kernel 4.13 and kernel 4.15
QP (num_queue_pairs) = 16 => ok all is ok with Kernel 4.13 but not with Kernel 4.15
