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.

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

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

ar71xx: Fix header offset for newer WRT160NL models
...
Newer WRT160NLs have a flash chip with 4K erase blocks instead of 64K,
resulting in miscalculated partition sizes.
Since the actual sizes did not change, hardcode them to their current
sizes, and make sure they are at least one erase block big (in case Cisco
decides to start to use chips with 128K erase blocks).

ar71xx: ag71xx: fix section mismatch warnings
...
The function __devinit ag71xx_probe() references
a function __devexit ag71xx_phy_disconnect().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
ag71xx_phy_disconnect() so it may be used outside an exit section.
The function ag71xx_phy_disconnect() references a function in an exit
section.
Often the function ag71xx_ar7240_cleanup() has valid usage outside the
exit section
and the fix is to remove the __devexit annotation of
ag71xx_ar7240_cleanup.
