At least one ar5211 card (GIGABYTE GN-WLMA101, 168c:0012 subsystem
1458:e800) reports itself as 11g capable which seems to be a bug in the
eeprom. initvals.c assumes that ar5211 is only 11b capable and thus refuses
to initialize this card. Hence this patch changes the probing for 11g
capabilities to discard 11g capabilities for ar5211 cards which allows this
specific card to work fine in 11b and 11a modes.

The stlc45xx chips are the only exception.

Under memory pressure, we may not be able to allocate a new skb for
new packets. If the allocation fails, ath5k_tasklet_rx will exit but
will leave a buffer in the list with a NULL skb, eventually triggering
a BUG_ON.
Extract the skb allocation from ath5k_rxbuf_setup() and change the
tasklet to allocate the next skb before accepting a packet.

Now that we're using iwl_mod_params, we want our module parameters names to be
in sync with the structure.
So, to set iwl_mod_params.sw_crypto, we'd better use a "swcrypto" parameter
name instead of the "hwcrypto" current one.
Moreover, by setting the decrypted flag properly, this patch also fixes the HW
crypto path for 3945 (the current code is not setting it when running HW
crypto).

* IEEE80211_HW_PS_NULLFUNC_STACK - indicates nullfunc sending in software
* IEEE80211_HW_SUPPORTS_DYNAMIC_PS - indicates dynamic PS on the device
It also adds documentation for all this which explains how to set the
various flags.
Additionally, it fixes a few things:

* enable CONF_PS only when associated again

As discussed on linux-wireless rt2x00 does not offer a true RFKILL key,
for that reason RFKILL support should be entirely removed.
The key which is attached to the hardware should be treated as normal
input device instead. Implement input_poll_dev support to poll the device
frequently. When the key status has changed report it as a SW event.
