Packet Priority & VLAN

Enables sending and receiving of IEEE 802.3ac tagged frames, which include:
802.1p QoS (Quality of Service) tags for priority-tagged packets
802.1Q tags for VLANs
Intel® PROSet automatically enables 802.1p tagging when you set up a VLAN. You 

cannot disable QoS Packet Tagging on a VLAN because tagging is required for VLANs.
When this feature is enabled, tagged packets use the queue settings defined by the 

operating system Priority Level Definition.
When this setting is disabled, the adapter cannot tag outgoing packets with 

802.1p/802.1Q tags.

Performance Options

Receive Descriptors or Receive Buffers

Sets the number of buffers used by the driver when copying data to the protocol 

memory. Increasing this value can enhance the receive performance, but also 

consumes system memory.
Receive Descriptors are data segments that enable the adapter to allocate received 

packets to memory. Each received packet requires one Receive Descriptor, and each 

descriptor uses 2 KB of memory.

Transmit Descriptors or Transmit Buffers

Defines the number of Transmit Descriptors, which are data segments that enable the 

adapter to track transmit packets in the system memory. Depending on the size of the 

packet, each transmit packet requires one or more Transmit Descriptors.
You might choose to increase the number of Transmit Descriptors if you notice a 

problem with transmit performance. Increasing the number of Transmit Descriptors 

can enhance transmit performance. But, Transmit Descriptors consume system 

memory. If transmit performance is not an issue, use the default setting.
