Eeprom read operations are mixed in the probe function.
Make the code more readable and clean by extracting this code and
moving it in a dedicated function.
The variable eeprom_cck_table_adr, now useless, is here because
it will be needed for rtl8187se support, that I hope to add soon.

SLOT, SIFS, DIFS, EIFS, CW and ACK-timeout registers are set in an
RF-code callback and their values are fixed.
This patch moves this off the rf-code, and introduce two new functions
that calculate these values depending by slot time and CW values
requested by mac80211.
This seems to improve performances on my setup.
Currently the ack and slot time values could be stored in a local
variable, but this patch stores it in the driver "priv" structure
because it will be useful for rtl8187se support that will be added
(hopefully) soon.

Basic rates setting is done with hardcoded register write with
fixed settings.
This patch introduces a new function that makes it possible to

BSS_CHANGED_BASIC_RATES flag in order to eventually invoke that
function when needed.

The nl80211 iftype was converted to a mode value and stored in
brcmf_cfg80211_vif structure. The value was used only within
brcmfmac driver to decide execution of conditional code. Better
use wireless_dev::iftype for that as the wdev is contained in
the brcmf_cfg80211_vif structure.

When connecting without specifying the channel it can take quite

SDIO tx uses a sequence number which is common for data

is protected. A mutex was used to achieve this, but it also
required the reordering of code for tx control.

This is the NFC pull request for 3.15. With this one we have:
- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel
now supports those through the NFC netlink and digital APIs.
- Support for TI's trf7970a chipset. This chipset relies on the NFC
digital layer and the driver currently supports type 2, 4A and 5 tags.
- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
relies on a different firmware download protocal than the C2 one. We
now support both and use the right one depending on the version we
detect at runtime.
- Support for 4A tags from the NFC digital layer.
- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande.

In order to restore the qos seq number on d0i3 exit,
we need to read it from the wowlan status.
However, in order to make sure we use correct seq num
for tx frames, we need to defer any outgoing frames,
and re-enqueue them only after the seq num is configured
correctly.
Sync new Tx aggregations with D0i3 so that the correct
seq num is used for them. Wait synchronously for D0i3
exit before starting a new Tx agg.

Non-QoS counter is handled internally in the fw, so
no need to configure it.

Enable beacon filter only if at least one beacon from candidate
AP is received before or after association. Check this condition before
enabling BF upon secured association completion. Add BF enablement to

Too early beacon filtering enablement can lead to disconnection due to
