The FTGMAC100 device is an Ethernet controller with DMA function that
can be found on Aspeed SoCs (which include NCSI).
It is fully compliant with IEEE 802.3 specification for 10/100 Mbps
Ethernet and IEEE 802.3z specification for 1000 Mbps Ethernet and
includes Reduced Media Independent Interface (RMII) and Reduced
Gigabit Media Independent Interface (RGMII) interfaces. It adopts an
AHB bus interface and integrates a link list DMA engine with direct
M-Bus accesses for transmitting and receiving packets. It has
independent TX/RX fifos, supports half and full duplex (1000 Mbps mode
only supports full duplex), flow control for full duplex and
backpressure for half duplex.
The FTGMAC100 also implements IP, TCP, UDP checksum offloads and
supports IEEE 802.1Q VLAN tag insertion and removal. It offers
high-priority transmit queue for QoS and CoS applications
This model is backed with a RealTek 8211E PHY which is the chip found
on the AST2500 EVB. It is complete enough to satisfy two different
Linux drivers and a U-Boot driver. Not supported features are :
- IEEE 802.1Q VLAN
- High Priority Transmit Queue
- Wake-On-LAN functions
The code is based on the Coldfire Fast Ethernet Controller model.

In migration codes (especially in migration_thread()), max_size is used
in many place for the threshold value that we will start to do the final
flush and jump to the next stage to dump the whole rest things to
destination. However its name is confusing to first readers. Let's
rename it to "threshold_size" when proper and add a comment for it. No
functional change is made.

If we close the QEMUFile descriptor in process_incoming_migration_co()
while it has been stopped by an error, the postcopy_ram_listen_thread()
can try to continue to use it. And as the memory has been freed
it is working with an invalid pointer and crashes.
Fix this by releasing the memory after having managed the error
case (which, in fact, calls exit())
