MFC r344990:

2019-03-28T09:50:25Z

Fix ieee80211_radiotap(9) usage in wireless drivers: - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers.

ipw(4): reuse ieee80211_tx_complete function This should partially fix 'netstat -b -I wlan0' output

Fix ipw_start(), where logic was reverted in r287197. PR: 232554

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

net80211 & wireless drivers: remove duplicate defines (noop)

2015-09-22T02:44:59Z

* IEEE80211_DIR_DSTODS(wh) -> IEEE80211_IS_DSTODS(wh). * N(a) -> nitems(a). * Remove LE_READ_2(p)/LE_READ_4(p) definitions (and include ieee80211_input.h instead). * _TXOP_TO_US(txop) -> IEEE80211_TXOP_TO_US(txop). * Put IEEE80211_RV(v) into ieee80211_proto.h and remove local RV(v) definitions.

Replay r286410. Change KPI of how device drivers that provide wireless

2015-08-27T08:56:39Z

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.

Convert more ifp->if_softc -> ic->ic_softc.

These should be a big no-op. Tested: * make universe

Revert the wifi ifnet changes until things are more baked and tested.

* 286410 * 286413 * 286416 The initial commit broke a variety of debug and features that aren't in the GENERIC kernels but are enabled in other platforms.
