Abstract
System and techniques for enhanced electronic navigation maps for a vehicle are described herein. A descriptor set-up message may be received at a network controller interface (NIC). Here, the descriptor set-up message includes an ethernet frame descriptor. The NIC may then use the ethernet frame descriptor to transmit, across a physical interface of the NIC, multiple ethernet frames, each of which use the same ethernet frame descriptor from the set-up message.
Claims24
A device for a fixed ethernet frame descriptor, the device comprising:
- a memory including instructions;
- and
- processing circuitry that, when in operation, is configured by the instructions to:
- receive a descriptor set-up message, the descriptor set-up message including an ethernet frame descriptor;
- store the ethernet frame descriptor in the device and placing the device into a fixed descriptor mode in response to receiving the descriptor set-up message;
- receive a set of transmission messages;
- and
- for each transmission message in the set of transmission messages:
- constructing an ethernet frame using the ethernet frame descriptor stored in the device;
- and
- transmitting, across a physical interface of the device, the ethernet frame.
At least one non-transitory machine-readable medium including instructions to implement a fixed ethernet frame descriptor, the instructions, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:
- receiving, at a network controller interface (MC) of a host device, a descriptor set-up message, the descriptor set-up message including an ethernet frame descriptor;
- storing the ethernet frame descriptor in the NIC and placing the MC into a fixed descriptor mode in response to receiving the descriptor set-up message;
- receiving, by the NIC, a set of transmission messages;
- and
- for each transmission message in the set of transmission messages:
- constructing an ethernet frame using the ethernet frame descriptor stored in the NIC;
- and
- transmitting, across a physical interface of the NIC, the ethernet frame.
