...and use it in hostap_cs and orinoco_cs.

Another PCMCIA device with Intersil Prism chipset has been reported:

Socket 0:
  product info: "Gigabyte", "GN-WLM01_P25L_ADAPTER", "ISL37300P", "Eval-RevA"
  manfid: 0x02e0, 0x1011
  function: 6 (network)

As it's the case with some other Prism based devices, the third ID
string contains a design name that should be sufficient to identify the
card as having Intersil Prism chipset and thus compatible with both
orinoco_cs and hostap_cs.

Introduce PCMCIA_DEVICE_PROD_ID3 that matches the third ID string only.

Use it in orinoco_cs and hostap_cs to match cards with the third ID
string indicating Prism chipset.  Remove corresponding entries that use
PCMCIA_DEVICE_PROD_ID123.

Support for rt30xx- and rt35xx-based devices is currently not functional
in rt2800pci and rt2800usb.
In order to not confuse users we shouldn't claim the PCI and USB device
ID's for these devices. However, to allow for testing it is good to still
have them available, although disabled by default.
Make support for these device configuration options that default to off.

For rt2800usb a 3rd class of devices is added, which are the unknown
devices. For these devices it is known that they are either based on
rt28xx, rt30xx or rt35xx, but it is not known on what chipset exactly.
These devices are disabled by default as well, until it can be established
on what chipset exactly they are based.

Adding support for setting the coverage class in some cases broke
association and data transfer, as it overwrote the initial ACK timeout
value from the initvals with a smaller value.
I don't know why the new value works in 5 GHz (matches the initval
there), but not in 2.4 GHz (initvals use 64us here), so until the
problem is fully understood, the value should be increased again.

This change monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the expected_
ack_count also drops.  At the same time, the aggregated ba_timeout (the number
of ba timeout retries) also rises.  If the actual_ack_count/expected_ack_count
ratio is 0 and the number of ba timeout retries rises to 16, no tx packets
(tcp, udp, or ping - icmp) can be delivered.  The driver recovers from this
situation by reseting the uCode firmware.  If the actual_ack_count/expected_
ack_count ratio drops below 50% (but not 0) and the aggregated ba_timeout
retries just exceed 5 (but not 16), then the driver can reset the radio to
bring the throughput up.

To ensure that card is in a sane state during probe we add a reset call.
This change was prompted by users of kdump who was not able to bring up the
wireless driver in the kdump kernel. The problem here was that the primary
kernel, which is not running at the time, left the wireless card up and
running. When the kdump kernel starts it is thus possible to immediately
receive interrupts from firmware after registering interrupt, but without
being ready to deal with interrupts from firmware yet.

There is a problem if an "internal short scan" is in progress when a
mac80211 requested scan arrives. If this new scan request arrives within
the "next_scan_jiffies" period then driver will immediately return success
and complete the scan. The problem here is that the scan has not been
fully initialized at this time (is_internal_short_scan is still set to true
because of the currently running scan), which results in the scan
completion never to be sent to mac80211. At this time also, evan though the
internal short scan is still running the state (is_internal_short_scan)
will be set to false, so when the internal scan does complete then mac80211
will receive a scan completion.

Fix this by checking right away if a scan is in progress when a scan
request arrives from mac80211.

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.
