Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.

All boards supported by this driver could work using PIO or MMIO for accessing
registers.
This driver tries to access HW by using MMIO, and, if this fails for somewhat
reason, the driver tries to fall back to PIO mode.
MMIO-mode is straightforward on all boards.
PIO-mode is straightforward on rtl8180 only.
On rtl8185 and rtl8187se boards not all registers are directly available in PIO
mode (they are paged).
On rtl8185 there are two pages and it is known how to switch page.
PIO mode works, except for only one access to a register out of default page,
recently added by me in the initialization code with patch:
rtl818x_pci: Fix rtl8185 excessive IFS after CTS-to-self
This can be easily fixed to work in both cases (MMIO and PIO).
On rtl8187se, for a number of reasons, there is much more work to do to fix PIO
access.
PIO access is currently broken on rtl8187se, and it never worked.
This patch fixes the said register write for rtl8185 and makes the driver to
fail cleanly if PIO mode is attempted with rtl8187se boards.
While doing this, I converted also a couple of printk(KERN_ERR) to dev_err(), in
order to make checkpatch happy.

Introduce a new function to configure AC parameters for TX queues
on rtl8187se cards, and hook it onto mac80211 in order to enable
WMM support.

rtl8180 has one register for analog converters setting ,rtl8185 has
two and rtl8187se has three.
Setting those registers require more than a simple write, and for
one of them a function is already provided.
This patch introduces functions for the other two.
rtl8187se will use them. rtl8185 doesen't yet, but should

This patch adds tx queue mapping for rtl8187se and a long comment
block about their usages.
It adapts the TX function to use that map and it sets properly
the TX descriptor rtl8187se-only fields

Currently RX status descriptor and RX command descriptor are
represented using the same struct type.
This patch splits this by introducing different types for
rx status and command descriptor.
Doing this make it possible to handle rtl8187se RX descriptors
easier.
This patch do also this by adding specific cases where needed.

This patch modifies the TX descriptor struct so it can work also
for rtl8187se.
Some reserved field is now meaningful, and where needed union is
used.

On currently supported HW there are four TX queues (three for normal
packets and one for beacons).
The driver uses just one TX queue, and declare to mac80211 to
support just one queue, but it allocates coherent memory for all
queues.
Furthermore the TX is code is written assumimg four queues exists,
and even if we decide to enable more queues in future, its mapping
rule to mac80211 is fixed.
This means we have memory waste on rtl8180/rtl8185, and we have also
not enough flexibility to add support for boards (rtl8187se) that
will use more queues.
This patch changes things in order to allocate coherent memory only
for the queues effectively used and it make it possible to specify
how to map hardware queues on mac80211 queues, that will be used
by rtl8187se code as soon it will be merged.
Note: even if the beacon queue is currently unused, this should
change, so I kept it.

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.

While changing board-type variable to enum, I have added enum
value for rtl8187se by mistake.
This will causes gcc warnings with unhandled switch/cases.

Currently a "r8185" integer variable is used as a boolean flag to
indicate whether the card is a rtl8185 or not.
Since now the driver supports only rtl8185 and rtl8180 cards, if
"r8185" variable is zero then the card is implicitly assumed to
be a rtl8180.
Now I'm preparing to add support for a third card type (rtl8187se).
This patch changes the "r8185" flag with an enum variable to
explicitly indicate which card type we have.
I'm submitting this this patch now, even if I still have to submit
other patches that not pertain with rtl8187se support, because
IMHO it's not worth rebasing them on the current code, using r8185
flag, and then changing them back again nearly immediately.
BTW if someone feels I really should do this, please tell me..

These drivers share one header file, but nothing else. Worse, both
drivers use the rtl8225 part with different register settings. The
results has been some ugly naming -- let's simplify that.
