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. Signed-off-by: John W. Linville <linville@tuxdriver.com>
