The idea was to keep private data related to 'wiphy priv'
in 'wilc_priv' struct and 'netdev priv' related data in 'wilc_vif'
struct.
I tried to follow this approach while preparing this patches series to
avoid use of these static variables mostly.
If you look at aging timer its related to deletion of wifi scan
results from the shadow list. So I moved it as part of wilc_priv. And
variable related to ip were more specific to netdev.
Actually for each interface a separate copy is maintained for wiphy_priv
and netdev_priv struct.
Anyways, if you have any suggestion let me know I try to include them
in future patches.
