The kernel already has this information, and individual drivers
shouldn't duplicate that. This also eliminates the use of __TIME__,
which makes the build non-deterministic. (And, without __DATE__,
__TIME__ provided little useful information to begin with.)

As of Matt Mooney's major refactoring in 2011, usbip port
option was left out. Add support for this option in
a manner similar to the old implementation.
Sample output:

Fast Channel Change across bands was enabled for
AR9462 recently, but this is causing baseband issues.
Disable it until this feature is tested well. Also,
remove the feature bit for AR9565 since it is
a single-band card and doesn't support this feature.

Accessing the current channel definition in mac80211
when processing RX packets is problematic because it
could have been updated when a scan is issued. Since a
channel change involves flushing the existing packets
in the RX queue before a chip-reset is done, they would
be processed using the wrong band/channel information.
To avoid this, use the current channel information
maintained in the driver.

Use hardware capabilities to limit IRQ generation to about 15 per msec
It corresponds to about 7 packets/IRQ when running iperf with default
parameters at 1.3Gbps
Do not enable this feature in the sniffer (monitor) mode, because
interrupt moderation cause timestamp accuracy deterioration.
For the sniffer flow, it is important to get precise timestamp.

The firmware doesn't support per packet encryption selection, so disable hw
encryption support completely while a monitor interface is present to support
injection of packets (which shouldn't get encrypted by hw).
To enforce the changed hw encryption support force a disassociation on
non-monitor interfaces.
For disassociation a workaround using hw connection monitor is employed,
which temporary enables hw connection manager flag.

Use the ENABLE_RX command for channel switching when no interface is present
(monitor mode only).
The advantage of ENABLE_RX is that it leaves the tx data path disabled in
firmware, whereas the usual JOIN command seems to transmit some frames at
firmware level.

With a dissasociated card I often encoutered very long scan delays.
My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.
Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.

Some DMA cores might add additional restrictions on which in memory audio
formats can be supported by the compound sound card. If the PCM component
specifies a set of formats it supports (by setting the formats field to non 0)
take these into account when calculating the format set for the compound sound
card.

The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.
