ETRAX_ETHERNET selects ETHERNET and MII, which depend on NETDEVICES. I don't think anything should select NETDEVICES, so make it a dependency. It also doesn't need to select or depend on ETHERNET, which has nothing to do with the Ethernet library functions. BPCTL selects MII, which depends on NETDEVICES. But everything in the drivers/staging/silicom directory is related to net devices, so make NET_VENDOR_SILICOM depend on NETDEVICES and remove the now-redundant dependencies on NET.
