algorithm to accomodate RSSI variation. Add a couple
of knobs to control low RSSI threshold and fast antenna
diversity bias values.

4965 version of Eric patch "iwl3945: better skb management in rx path".
It fixes several problems :

1) skb->truesize is underestimated.
   We really consume PAGE_SIZE bytes for a fragment,
   not the frame length.
2) 128 bytes of initial headroom is a bit low and forces reallocations.
3) We can avoid consuming a full page for small enough frames.

Whenever available, use cfg80211_scan_request to populates rates
in outgoing probe request. This will help to advertise band specific
rates and fix an issue where 11b rates were advertised in probe
request going out on 11a band.

This will also ensure that we do not advertise 11b rates while P2P

It has introduced by recent commit 6b41f941: "mwifiex:
handle driver initialization error paths" which adds error
path handling for mwifiex_fw_dpc().

release_firmware(adapter->*) is called for success as well
as failure paths. In failure paths, adapter is already freed
at this point.

The issue is fixed by moving mwifiex_free_adapter() call.

If fw_restart is disabled, using the fw_restart debugfs
file will enable fw_restart and then send the failing
command, but this still frequently fails restart because
it resets fw_restart afterwards and is thus racy.

Fix this by tracking fw_restart separately and allowing
"always restart", "never restart" and "restart N times".

If we get a firmware error during restart, we currently abandon any
hope and simply fail, getting stuck until the driver is reloaded.
Unfortunately, there isn't really much else we can do since restart
will likely continue to fail, and asking mac80211 for disconnection
just causes more error.

To allow the user to at least set up the device again completely
from scratch, reprobe the device and in doing so completely destroy
any mac80211/driver state.
