support for virtualization feature called Virtual Machine Data queue (VMDq), which
improves I/O performance by reducing I/O overhead in a virtualized environment.
802.1Q VLANs with 802.1p
QoS Tagging
IEEE 802.1Q virtual local area network (VLAN) protocol allows each physical port to be
separated into multiple virtual NICs for added network segmentation and enhanced security and
performance. VLANs increase security by isolating traffic between users. Limiting the broadcast traffic to
within the same VLAN domain also improves performance. IEEE quality of service (QoS) 802.1p tagging
allows the adapter to mark or tag frames with a priority level across a QoS-aware network for improved
flow
