Widen EPOCH(9) usage in PCI WLAN drivers. Make sure all occurrences of ieee80211_input_xxx() in sys/dev are covered by a network epoch section. Do not depend on the interrupt handler nor any taskqueues being in a network epoch section. This patch should unbreak the PCI WLAN drivers after r357004.

[net80211] convert all of the WME use over to a temporary copy of WME info. This removes the direct WME info access in the ieee80211com struct and instead provides a method of fetching the data. Right now it's a no-op but eventually it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm, upcoming ath10k work) as things like p2p support require this kind of behaviour. Tested: * ath(4), STA and AP mode TODO: * yes, this is slightly stack size-y, but it is an important first step to get drivers migrated over to a sensible WME API. A lot of per-phy things need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up.

net80211 drivers: fix rate setup for EAPOL frames, obtain Tx parameters directly from the node. - Use ni_txparms directly instead of calculating them manually every time - Move M_EAPOL flag check upper; otherwise it may be skipped due to 'ucastrate' / 'mcastrate' check - Use 'mgtrate' for control frames too (see ifconfig(8), mgtrate parameter) - Add few more M_EAPOL checks where it was missing (zyd(4), ural(4), urtw(4)) - Few unrelated cleanups Tested with: - Intel 6205 (iwn(4)), STA mode; - WUSB54GC (rum(4)), HOSTAP mode + RTL8188EU (rtwn(4)), STA mode.

net80211: ieee80211_ratectl*: switch to reusable KPI Replace various void * / int argument combinations with common structures: - ieee80211_ratectl_tx_status for *_tx_complete(); - ieee80211_ratectl_tx_stats for *_tx_update(); While here, improve amrr_tx_update() for a bit: 1. In case, if receiver is not known (typical for Ralink USB drivers), refresh Tx rate for all nodes on the interface. 2. There was a misuse: - otus(4) sends non-decreasing counters (as originally intended); - but ural(4), rum(4) and run(4) are using 'read & clear' registers to obtain statistics for some period of time (and those 'last period' values are used as arguments for tx_update()). If arguments are not big enough, they are just discarded after the next call. Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.

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

Implement basic 802.11n awareness in the PHY and AMRR rate control code. * Add 802.11n 2ghz and 5ghz tables, including legacy rates and up to MCS23 rates (3x3.) * Populate the rate code -> rate index lookup table with MCS _and_ normal rates, but _not_ the basic rate flag. Since the basic rate flag is the same as the MCS flag, we can only use one. * Introduce some accessor inlines that do PLCP and rate table lookup/access and enforce that it doesn't set the basic rate bit. They're not designed for MCS rates, so it will panic. * Start converting drivers that use the rate table stuff to use the accessor inlines and strip the basic flag. * Teach AMRR about basic 11n - it's still as crap for MCS as it is being used by iwn, so it's not a step _backwardS_. * Convert iwn over to accept 11n MCS rates rather than 'translate' legacy to MCS rates. It doesn't use a lookup table any longer; instead it's a function which takes the current node (for HT parameters) and the rate code, and returns the hardware PLCP code to use. Tested: * ath - it's a no-op, and it works that way * iwn - both 11n and non-11n
