Intel X710 for 10GbE SFP+ drops all packets


Server platform:

Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz x 2


3.10.0-123.el7.x86_64 kernel, CentOS 7

Intel X710 card (4x10Gbps) drops all ingress packets. ethtool port rx_dropped counter increases, ifconfig shows there are no any packets available for this port.
