[PATCH 1/3] dsa: Remove unnecessary exports

[PATCH 1/3] dsa: Remove unnecessary exports

[Ben Hutchings]

I mistakenly exported functions from slave.c that are only called from
dsa.c, part of the same module.

[PATCH net-next 2/3] dsa: Move all definitions needed by drivers into <net/dsa.h>

[Ben Hutchings]

Any headers included by drivers should be under include/, and
any definitions they use are not really private to the core as
the name "dsa_priv.h" suggests.

[PATCH net-next 3/3] dsa: Move switch drivers to new directory drivers/net/dsa

This seems to work, but again it's compile-tested only.
