I don't see the appropriate changes in your patches to make
sure that drivers/net/ethernet/{Kconfig,Makefile} consider
and traverse down into the wiznet/ subdirectory.

Furthermore, once that is fixed these drivers generate warnings
when built:

drivers/net/ethernet/wiznet/w5300.c:708:8: warning: initialization from incompatible pointer type [enabled by default]

drivers/net/ethernet/wiznet/w5300.c:708:8: warning: (near initialization for ‘w5300_pm_ops.restore’) [enabled by default]

It seems that the arguments and return types for these operations have
changed since you worked on these patches, but this should be easy
to fix up.

Please cure these two issues and I'll happily put these new drivers
into net-next, and meanwhile you can continue to work with Eric
Dumazet to correct the TX flow control and locking issues.

Thanks.
