Improve mxge watchdog routine's ability to reliably reset a failed NIC:
- Mark the link as down, so if watchdog reset fails, link watching failover software can notice it - Don't send MXGEFW_CMD_ETHERNET_DOWN if the NIC has been reset, it is not needed, and will fail on a freshly reset NIC. - Ensure the transmit routines aren't attempting to PIO write to doorbells while the NIC is being reset. - Download the correct f/w, rather than using the EEPROM f/w after reset. - Export a count of the number of watchdog resets via sysctl - Zero all f/w stats at reset. This will lead to less confusing diagnostic output when investigating NIC failures. MFC after: 3 days
