ibm_emac: Convert to use napi_struct independent of struct net_device
Commit da3dedd9 ("[NET]: Make NAPI polling independent of struct net_device objects.") changed the interface to NAPI polling. Fix up the ibm_emac driver so that it works with this new interface. This is actually a nice cleanup because ibm_emac is one of the drivers that wants to have multiple NAPI structures for a single net_device. Tested with the internal MAC of a PowerPC 440SPe SoC with an AMCC 'Yucca' evaluation board. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
