Several small fixes for ar8216 driver (patch by Jonas Gorski)
* Create defines for some magic values/masks. * Change vlan_id to u16, to allow VIDs > 255. * Add a range check to set_pvid as it isn't a VID, but the index in the vlan table. * Set the max VID to 4094, since 4095 is a reserved value and should not be used. * In mangle_rx replace the provided VID with the VID of the table entry of the port, not the index of the table. * In hw_apply, remove a redundant emptyness check (was already checked several lines above). * In no vlan mode do not set the ingress mode to secure, as there are no vlan table entries, but to use the port's destination masks. Otherwise the switch won't forward anything. * In read_status tell that the phy is up (taken from the rtl8306 driver). SVN-Revision: 20083
