mac80211: support use of NAPI for bottom-half processing
This patch implement basic infrastructure to support use of NAPI by
mac80211-based hardware drivers.
Because mac80211 devices can support multiple netdevs, a dummy netdev
is used for interfacing with the NAPI code in the core of the network
stack. That structure is hidden from the hardware drivers, but the
actual napi_struct is exposed in the ieee80211_hw structure so that the
poll routines in drivers can retrieve that structure. Hardware drivers
can also specify their own weight value for NAPI polling.
