Gabor Juhos 5d77f370d6 ar71xx: ag71xx: make switch register access atomic ... Reading of the PHY registers occasionally returns with bogus values under heavy load. This misleads the PHY driver and thus causes false link/speed change notifications which leads to performance loss. This is easily noticable during an iperf session: ...

Makefile	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 fixes #7563	2010-08-16 19:21:57 +00:00
