libertas: Fine grained configuration of wake-on-lan.

Browse Source 
Based on a patch from Shailendra Govardhan <shailen@marvell.com>.
This patch allows implementation of more specific wake-on-lan rules than those
of ethtool.

Please note that only firmware 5.110.22.p20 and above supports this feature.

This patch only implements the driver/firmware interface, not the
userspace/driver interface.
