Abstract
A method of configuring a port on a network device includes receiving a frame of information, determining that the frame includes maximum transmission unit (MTU) information, and configuring a prioritized receive queue on the port with an MTU size based on the MTU information. The MTU size is different than another MTU size of another prioritized receive queue on the port. A network interface includes a port, a de-multiplexer coupled to an output or the port, and prioritized receive queues that each have an MTTU size. A first prioritized receive queue has an MTU size different than a second prioritized receive queue.
Claims20
A method of configuring a port on a network device, comprising:
- receiving at the network device a first frame of information;
- determining that the first frame of information includes first maximum transmission unit (MTU) information;
- and
- configuring a first prioritized receive queue of a plurality of prioritized receive queues on the port with a first MTU size based upon the first MTU information, wherein the first MTU size is different than a second MTU size of a second prioritized receive queue of the plurality of prioritized receive queues.
Machine-executable code for an information handling system having a first resource, wherein
- the machine-executable code is embedded within a tangible medium and includes instructions for carrying out a method comprising:
- receiving a first frame of information;
- determining that the first frame of information includes first maximum transmission unit (MTU) information;
- and
- configuring a first prioritized receive queue of a plurality of prioritized receive queues on a network port with a first MTU size based upon the first MTU information, wherein the first MTU size is different than a second MTU size of a second prioritized receive queue of the plurality of prioritized receive queues.
A network interface comprising:
- a port including a first input operably coupleable to an Ethernet network, and a first output;
- a de-multiplexer including a second input and a plurality of second outputs, the second input being coupled to the first output of the port;
- and
- a plurality of prioritized receive queues, each of the plurality of prioritized receive queues including a third input and a third output, each third input being coupled to one of the plurality of second outputs of the de-multiplexer, wherein each of the plurality of prioritized receive queues has a maximum transmission unit (MTU) size, and wherein a first prioritized receive queue has an MTU size different than a second prioritized receive queue.
