And some minor bugfixes.

Known limitations:

Incorrect reporting of link speed on older/DPDK VF drivers
For i40evf/iavf drivers older than 3.9.3 and all DPDK i40e VF drivers, this driver needs to be built with extra parameter (make CFLAGS_MODULE='-DNO_VF_CAP_ADV_LINK_SPEED') in order to enable correct reporting of the link speed for VFs. This will have side effect of incorrect reporting link speeds of 2,5 and 5 Gbps.

Limited support of 802.1ad VLAN traffic
For packets tagged per 802.1ad standard (QinQ) certain SR-IOV Hypervisor Management Interface features like vlan_mirror and trunk will not work.

VFs inability to capture packets directed to another VF
Virtual functions will not be able to capture packets with destination MAC of another VF unless vf-true-promisc-support private flag is set.

vlan_anti_spoof doesn't affect ability to send untagged packets
When vlan_anti_spoof option is set using SR-IOV Hypervisor Management Interface, Virtual Functions will be still able to send packets without VLAN tags.

Limited capabilities of viewing MAC address list
Because of the buffer size limit (kernel limitation) it is possible to add more MAC addresses to the mac_list then it is possible to display using #cat.
Therefore it is not recommended to add more than 180 MAC addresses.

Maximum queue number per VF
num_queues feature of SR-IOV Hypervisor Management Interface has no protection against overutilization of the available queues among VFs.
