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

5cc1f4bcf3 ar71xx: add a new driver for the ar7240 switch using swconfig. 
hooks directly into the ethernet driver, as MAC resets also require switch reinitializations and the switch is part of the cpu core anyway
switch only tl-wr741nd (and other devices using this board file, such as tl-wr841nd) over to using this by default, as other devices are still untested

c74f817d15 ar71xx: ag71xx: call the phy driver's netif_receive_skb() 
Ag71xx needs to call the phy's netif_receive_skb() to allow phy drivers
to mangle rx packets. This patch fixes it.

This fixes the header mangling of the AR8216 driver.
