The ERP configuration is now done outside RF code in both rtl8180
and rtl8187 drivers.
The conf_erp callback in common RF ops struct is now useless.
Remove 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.

Basic rates setting is done with hardcoded register write with
fixed settings.
This patch introduces a new function that makes it possible to
configure basic rates and it add a check for mac80211
BSS_CHANGED_BASIC_RATES flag in order to eventually invoke that
function when needed.

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..

The TX descriptors are consumed by the HW using DMA.
Even if in the driver code the TX descriptor writes appears before
the HW "dma kick" register writes, the CPU may reorder them.
If this happens, the TX may not happen at all becase the "valid"
descriptor flag may have not been set yet.
This patch adds a write memory barrier to ensures the TX
descriptor is written before writing to the HW "dma kick" register.

The TX descriptors are consumed by the HW using DMA.
Even if in the driver code the memory write that sets the "valid"
flag appears after all other writes, the CPU may reorder writes,
causing the HW to consider as valid a not-fully-written yet
descriptor.
This may cause HW incorrect behaviour.
This can happen because (AFAIK) the HW may attempt DMA
asynchronously without waiting to be kicked by the following
register write.
This patch adds a write memory barrier to enforce writes ordering.

Certain HW options (TX packet retry count, CW configuration and
TX power configuration) can be specified in both the TX packet
descriptor and also into HW "global" registers.
The HW is thus configured to honour the global register or the
TX descriptor field depending by the case.
This patch adds few comments that hopefully clarify in which cases
the driver uses one method and in which cases it uses the other.

During driver initialization, some skbs are preallocated for RX.
Currenly if the allocation fails, the driver's allocation routine
exits immediatly but it will return zero (success) anyway.
In this way the driver will continue initialization with buggy
pointers around.
This patch makes the driver's allocation routine to return
an error value and to print a complaint message when skb allocation
fails.
In this way its caller will not go further, avoinding the driver to
successfully load, and preventing dereferencing buggy pointers.
An hint is thus printed about why the driver failed.

During initialization a number of RX skbs are allocated and mapped
for DMA.
Currently if pci_map_single() fails, it will result in passing to the
HW a wrong DMA address (to write to!).
This patch adds check for this condition and eventually causes the
driver not to initialize, avoiding at least dangerous DMAs.

This patch fixes regression caused by commit a16dad77634 "MIPS: Fix
potencial corruption". That commit fixes one corruption scenario in
cost of adding another one, which actually start to cause crashes
on Yeeloong laptop when rtl8187 driver is used.
For correct DMA read operation on machines without DMA coherence, kernel
have to invalidate cache, such it will refill later with new data that
device wrote to memory, when that data is needed to process. We can only
invalidate full cache line. Hence when cache line includes both dma
buffer and some other data (written in cache, but not yet in main
memory), the other data can not hit memory due to invalidation. That
happen on rtl8187 where struct rtl8187_priv fields are located just
before and after small buffers that are passed to USB layer and DMA
is performed on them.
To fix the problem we align buffers and reserve space after them to make
them match cache line.
This patch does not resolve all possible MIPS problems entirely, for
that we have to assure that we always map cache aligned buffers for DMA,
what can be complex or even not possible. But patch fixes visible and
reproducible regression and seems other possible corruptions do not
happen in practice, since Yeeloong laptop works stable without rtl8187
driver.

In rtl8180/rtl8187 drivers, few register bit definitions have
names of form FOOBAR_SHIFT, suggesting they should be used as
shift offset, for example
reg |= (1 << ENABLE_FOO_SHIFT).
However they are actually defined as (1 << x) and thus they are
used (correctly) like
reg |= ENABLE_FOO_SHIFT;
This patch kills the misleading _SHIFT suffix.

In original code the old RX DMA buffer is unmapped and processed and at the end
of the isr a new buffer is mapped with pci_map_single and attached to the RX
descriptor.
If pci_map_single fails then the RX descriptor remains with no valid DMA buffer
attached.
In this condition the DMA will target where it shouldn't with obvious evil
consequences.
Simply avoiding re-arming the descriptor will prevent buggy DMA but it will
result soon in RX stuck.
This patch move the DMA mapping of the new buffer at the beginning of the ISR
(and it adds error check for pci_map_single success/fail).
If the DMA mapping fails then we do not unmap the old buffer and we re-arm the
descriptor without processing it, with the old DMA buffer still attached.
In this way we lose the currently RX-ed packet, but whenever next calls to
pci_map_single will succeed again,then the RX process will go on without stuck.

There are also lots of new drivers, pimarily gadget, but others as

Hub-initiated LPM is not good for USB communications devices. Comms
devices should be able to tell when their link can go into a lower power
state, because they know when an incoming transmission is finished.
Ideally, these devices would slam their links into a lower power state,
using the device-initiated LPM, after finishing the last packet of their
data transfer.
If we enable the idle timeouts for the parent hubs to enable
hub-initiated LPM, we will get a lot of useless LPM packets on the bus
as the devices reject LPM transitions when they're in the middle of
receiving data. Worse, some devices might blindly accept the
hub-initiated LPM and power down their radios while they're in the
middle of receiving a transmission.
The Intel Windows folks are disabling hub-initiated LPM for all USB
communications devices under a xHCI USB 3.0 host. In order to keep
the Linux behavior as close as possible to Windows, we need to do the
same in Linux.
Set the disable_hub_initiated_lpm flag for for all USB communications
drivers. I know there aren't currently any USB 3.0 devices that
implement these class specifications, but we should be ready if they do.

The device.h header was including module.h, making it present for
most of these drivers. But we want to clean that up. Call out the
include of module.h in the modular network drivers.

tx params should be configured per interface.
add ieee80211_vif param to the conf_tx callback,
and change all the drivers that use this callback.
The following spatch was used:

TSF can be kept per vif.
Add ieee80211_vif param to set/get/reset_tsf, and move
the debugfs entries to the per-vif directory.
Update all the drivers that implement these callbacks.

* remove interrupt.g inclusion from netdevice.h -- not needed
* fixup fallout, add interrupt.h and hardirq.h back where needed.

The driver for the RTL8187L chips returns IEEE80211_TX_STAT_ACK for all
packets, even if the maximum number of retries was exhausted. In addition
it fails to setup max_rates in the ieee80211_hw struct, This behavior
may be responsible for the problems noted in Bug 14168. As the bug is very
old, testers have not been found, and I do not have the case where the
indicated signal is less than -70 dBm.

The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).
Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.
Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

The flag isn't very descriptive -- the intention
is that the driver provides a TSF timestamp at
the beginning of the MPDU -- make that clearer
by renaming the flag to RX_FLAG_MACTIME_MPDU.

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.

Current 8187B initialization misses anaparam registers restore after
8187 reset. This causes ANAPARAM register to stay zeroed out (ANAPARAM2
kept its value on my tests). To avoid this, call rtl8187_set_anaparam
right after chip reset (to be on the safe side, as it makes sure we
restore all ANAPARAM registers).
