Subject: emaclite: enable transmit and receive time stamping.

This patch enables software (and phy device) time stamping. Since this
MAC uses phylib, adding the hooks make hardware time stamping in the phy
possible.

Compile tested only.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unnecessary casts of void * clutter the code.

These are the remainder casts after several specific
patches to remove netdev_priv and dev_priv.

Done via coccinelle script (and a little editing):

$ cat cast_void_pointer.cocci
