A couple of functions used with scan events were named with term "send" although they were only preparing the the event message so renamed those.

由 Michał Kępień 提交于
Add a new "global" (i.e. not per-rfkill device) LED trigger, rfkill-any, which may be useful on laptops with a single "radio LED" and multiple radio transmitters. The trigger is meant to turn a LED on whenever there is at least one radio transmitter active and turn it off otherwise. This requires taking rfkill_global_mutex before calling rfkill_set_block() in rfkill_resume(): since __rfkill_any_led_trigger_event() is called from rfkill_set_block() unconditionally, each caller of the latter needs to take care of locking rfkill_global_mutex.

由 Michael Braun 提交于
Add the ability for an AP (and associated VLANs) to perform multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames (possibly within 802.1Q). If enabled, such frames are to be sent to each station separately, with the DA replaced by their own MAC address rather than the group address. Note that this may break certain expectations of the receiver, such as the ability to drop unicast IP packets received within multicast L2 frames, or the ability to not send ICMP destination unreachable messages for packets received in L2 multicast (which is required, but the receiver can't tell the difference if this new option is enabled.) This also doesn't implement the 802.11 DMS (directed multicast service).
