Memory Allocation Failures on Transmit

Before transmitting data, the driver reserves system memory for a buffer to hold the data to be transmitted. Once the card is ready, the buffer is sent to it.

When a memory-allocation error occurs, the system is likely very low on memory. Make sure that there's sufficient memory on the system; if you continuously get this error, consider adding more memory. Another thing to check for is memory leaks on the system, which may be slowly consuming system memory.
