When setting fragmented skb for Tx, assign skb to the last descriptor
and set number of fragments in the 1-st one
On Tx complete, HW sets "DU" bit in Tx descriptor only for the last
descriptor; so search for it using number of fragments field.
Middle descriptors may have "DU" bit not set by the hardware.

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.

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 the SDIO driver goes in low power state it must assure that
a clock request in ChipCLKCSR is set. Otherwise waking up the

When connecting without specifying the channel it can take quite
some time to connect. This is because not all parameters for the
scan operation are set to optimized values. This patch changes
these parameters resulting in a much faster connect in certain
situations.

SDIO tx uses a sequence number which is common for data
and control. This requires that access to this sequence number
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.
