4.1.7.1. Remote Device Congestion

When the MAC function receives an XOFF pause frame and the PAUSE_IGNORE bit in the command_config register is set to 0, the MAC function completes the transfer of the current frame and stops transmission for the amount of time specified by the pause quanta in 512 bit times increments. Transmission resumes when the timer expires or when the MAC function receives an XON frame.

You can configure the MAC function to ignore pause frames by setting the PAUSE_IGNORE bit in the command_config register is set to 1.
