The previous patch changed the code so that new rx buffer submissions to
the hardware stall if a new submission would overwrite data needed by an
unserviced rx packet. On very busy 5717 and 57765 asic rev devices,
there is a corner case where the hardware will fail to assert an MSI-X
interrupt for rx traffic. If that vector's interrupt never has another
reason to assert, any rx buffers held will never be serviced. If the
buffers are never serviced and the hardware consumes all the available
rx packets for other rx rings, deadlock will result.
The most reliable and least intrusive way to work around the problem is
to detect the case where new submissions would overwrite existing data
and force all rx interrupt vectors to fire.

The following patch will require that this ring have a place to put

To avoid the interrupt handler waking the transmit queue while

Commit 357d46a17e "sfc: QT202x: Remove
unreliable MMD check at initialisation" broke initialisation of the
SFE4002. efx_mdio_reset_mmd() returns a positive value rather than 0
on success. The above commit causes this value to be propagated up
by qt202x_reset_phy(), which is treated as a failure by its callers.
Change qt202x_reset_phy() to return 0 if successful.
The PCI layer treats >0 as "fail, but please call remove() anyway",
which means that unloading the driver would cause a crash. Add a

This is a new network driver for Micrel KSZ8841/KSZ8842 PCI Ethernet chips. The same driver can run both chips at the same time. It supports IPv4 TCP hardware checksumming and so can use scatter/gather transmission.
The KSZ8842 switch has 2 ports. Some users like to take direct control of those ports. So KSZ8842 has a multiple devices mode in which the driver creates another network device so that users can specify which port to send packets. This mode is enabled by passing the "multi_dev=1" parameter to the driver during loading.
The KSZ884X can receive huge frames with size up to 1916 bytes. To use this feature change the network device MTU from 1500 to 1898.
The KSZ884X driver has 3 packet receive processing functions for the normal mode, multiple devices mode, and huge frame mode. Those functions are identical except for more checking for the new features. In normal programming point of view the huge frame version is the one to use because it covers all the cases, but this is done for performance consideration because the target clients for the KSZ884X chips are embedded systems, which unlike desktop PC may not have powerful CPU.

This patch fixes two potential races in the velocity driver:
* Move the ACK and error handler to the interrupt handler. This fixes a
potential race with shared interrupts when the other device interrupts
before the NAPI poll handler has finished. As the velocity driver hasn't
acked it's own interrupt, it will then steal the interrupt from the
other device.
* Use spin_lock_irqsave in velocity_poll. In the current code, the
interrupt handler will deadlock if e.g., the NAPI poll handler is
executing when an interrupt (for another device) comes in since it
tries to take the already held lock.
Also unlock the spinlock only after enabling the interrupt in
velocity_poll.
The error path is moved to the interrupt handler since this is where the
ISR is checked now.

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset). As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

6x50 device requires a different scaling factor for Rx gain values sent to
device via PHY_CALIBRATION_CMD (CHAIN_NOISE_GAIN_CMD). Rather than create
a new iwlXXXX_gain_computation() function, add new chain_noise_scale member
to struct iwl_cfg, and keep using iwl5000_gain_computation().

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.
Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

mac80211 uses unit units of 32 usec with txop but wl1251_acx_ac_cfg()
expects it to be usecs. This fortunately didn't cause any severe problems,
only that firmware was using incorrect WMM settings.

If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.
In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

The TIM timer interrupt is enabled even before the ACK of nullqos
is received which is unnecessary.
Also clean up the CONF_PS part of config callback properly for
better readability.

For debugging hardware scan trigger/complete
functionality, it was useful to have code in
hwsim that pretends to do a hardware scan.
This code could be extended to actually do the
scan, but for now it was sufficient for me to
only pretend. Since hwsim was written to ease
debugging, it only makes sense to add it to it
permanently.

iwl_set_rxon_ht() only get called in iwl_post_associate(); which cause
possible incorrect ht configuration. Adding the call in iwl_mac_config() if
IEEE80211_CONF_CHANGE_CHANNEL flag is set to re-configure and send rxon
command.
