661316a678 ar71xx: ag71xx: fix mii_bus_dev sanity check 
The mii_bus device is not required if phy_mask is zero.
The driver will use a fixed connection if it is not
specified.

d066413d5d ag71xx: close a race between the phy state machine and link state 
A fast stop/start cycle could leave the ag71xx interrupts and tx engine
disabled when using a phy driver with a fixed link and the start/stop
happens between two phy state machine polls.

Prevent this by always forcing the link down on stop regardless of phy
state and having a phy connected.

571d12ab3a ar71xx: fix ethernet FIFO state corruption on ar7240 
When starting/stopping DMA sometimes the FIFO state gets corrupted,
leading to wildly fluctuating latencies or packet data corruption.
Fix this by issuing a fast MAC reset as soon as the link is detected
as up. Fixes #9689, #9405

27818ae524 ag71xx: fix memory corruption issues on ar7240 on ethernet start/stop 
When the DMA engine state gets corrupted due to a hardware issues, it
often won't stop rx until a full reset is issued. In that case the hardware
must keep a valid descriptor, otherwise it will write to random places in
system RAM, triggering random crashes. To fix this, keep a dummy descriptor
without a buffer that keeps the DMA engine in a sane state until the reset
is done
