* cfg80211: Add support for QoS mappingKyeyoon Park2013-12-191-0/+62
| | | | | | | | | | | | | | | | | This allows QoS mapping from external networks to be implemented as defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise DSCP ranges and exceptions for mapping frames to a specific UP over Wi-Fi. The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97) is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to configure the local behavior either on the AP (based on local configuration) or on a station (based on information received from the AP).

* nl80211: support vendor-specific eventsJohannes Berg2013-12-191-19/+79
| | | | | | | | | | In addition to vendor-specific commands, also support vendor-specific events. These must be registered with cfg80211 before they can be used. They're also advertised in nl80211 in the wiphy information so that userspace knows can be expected. The events themselves are sent on a new multicast group called "vendor".

| * | genetlink: make multicast groups const, prevent abuseJohannes Berg2013-11-191-75/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns.

The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.)
