* Replay r286410. Change KPI of how device drivers that provide wirelessGleb Smirnoff2015-08-272-208/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | connectivity interact with the net80211 stack. Historical background: originally wireless devices created an interface, just like Ethernet devices do. Name of an interface matched the name of the driver that created. Later, wlan(4) layer was introduced, and the wlanX interfaces become the actual interface, leaving original ones as "a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer and a driver became a mix of methods that pass a pointer to struct ifnet as identifier and methods that pass pointer to struct ieee80211com. From user point of view, the parent interface just hangs on in the ifconfig list, and user can't do anything useful with it. Now, the struct ifnet goes away. The struct ieee80211com is the only KPI between a device driver and net80211. Details: - The struct ieee80211com is embedded into drivers softc. - Packets are sent via new ic_transmit method, which is very much like the previous if_transmit. - Bringing parent up/down is done via new ic_parent method, which notifies driver about any changes: number of wlan(4) interfaces, number of them in promisc or allmulti state. - Device specific ioctls (if any) are received on new ic_ioctl method. - Packets/errors accounting are done by the stack. In certain cases, when driver experiences errors and can not attribute them to any specific interface, driver updates ic_oerrors or ic_ierrors counters. Details on interface configuration with new world order: - A sequence of commands needed to bring up wireless DOESN"T change. - /etc/rc.conf parameters DON'T change. - List of devices that can be used to create wlan(4) interfaces is now provided by net.wlan.devices sysctl. Most drivers in this change were converted by me, except of wpi(4), that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann, Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Reviewed by: adrian Sponsored by: Netflix Sponsored by: Nginx, Inc.

Thanks to Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in testing. Details here: https://wiki.freebsd.org/projects/ifnet/net80211 Still, drivers: ndis, wtap, mwl, ipw, bwn, wi, upgt, uath were not tested. Changes to mwl, ipw, bwn, wi, upgt are trivial and chances of problems are low. The wtap wasn't compilable even before this change. But the ndis driver is complex, and it is likely to be broken with this commit. Help with testing and debugging it is appreciated. Differential Revision: D2655, D2740 Sponsored by: Nginx, Inc.

* Introduce wtap, the beginnings of a net80211 wlan simulator.Adrian Chadd2012-01-1113-0/+2339
This introduces: * a basic wtap interface * a HAL, which implements an abstraction layer for implementing different device behavious; * A visibility plugin, which allows for control over which nodes see other nodes (useful for mesh work.) It doesn't yet implement sta/adhoc/hostap modes but these are quite feasible to implement. Monthadar uses it to do 802.11s mesh verification. The userland tools will be committed in a follow-up commit. Submitted by: Monthadar Al Jaberi <monthadar@gmail.com> Notes: svn path=/head/; revision=229970
