The chip executes microcode present in internal RAM,
whose content is loaded from EEPROM on power cycle.
This patch allows an update of the microcode through PIO
without forcing a power cycle.

Under rare conditions, the MAC might hang while generating a pause frame.
This patch fine tunes the MAC settings to avoid the issue, allows for
periodic MAC state check, and triggers a recovery if hung.
Also fix one MAC statistics counter for the rev board T3B2.
