The current bcm43xx driver does not contain code to handle PCI-E interfaces
such as the BCM4311 and BCM4312. This patch, originally written by Stefano
Brivio adds the necessary code to enable these interfaces.

NET: prism54 - fix potential race in reset scheduling
There appears to be a race in reset scheduling logic - thread
responsible for reseting the interface should clear "reset
pending" flag before restarting the queue, otherwise timeout
handler might not schedule another reset even if it is needed.
This race is mostly theoretical as far as I can see but a race
nonetheless.

This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that
ieee80211_rx should strip the IV/ICV/other security features from the payload.
This saves on some memmove() calls in the driver and seems like something that
belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw
I will submit the ipw2200 patch separately as it needs testing.
This patch also adds some sensible variable reuse (idx vs keyidx) in

etherh and a handful of other odd drivers use different macros when building
8390.c. Since we generate a single 8390.o and then link with it, in any
config with both oddball and normal 8390-based driver we will end up with
breakage in at least one of them. Solution: take most of 8390.c into
lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it.
Helper macros are taken from 8390.h to whoever includes lib8390.c. That
way odd drivers get separate instances of compiled 8390 stuff and stop
stepping on each other's toes. 8390.h gets cleaned up - we don't have
the cascade of ifdefs in there and are left with the stuff that can be
used by any 8390-based driver. Current problems are exactly because of
that cascade - we attempt to choose the set of helpers by looking at config
and that, of course, doesn't work well when we have several sets needed
by various drivers in our config.

Tobias Diedrich <ranma@tdiedrich.de> sayeth:
Vanilla forcedeth doesn't seem to support suspend and an ifdown/up-cycle is
needed to get it working again after suspend. Francois Romieu's "Awfully
experimental" patch is working just fine for me (with message signalled
interrupts disabled) and has survived quite a few suspend/resume cycles.
So I'd very much like to see (at least partial, with msi disabled)
suspend support for forcedeth in mainline.

This patch fixes a couple of problems discovered with interrupt handling
in the phylib core, namely:
1. The driver uses timer and workqueue calls, but does not include
<linux/timer.h> nor <linux/workqueue.h>.
2. The driver uses schedule_work() for handling interrupts, but does not
make sure any pending work scheduled thus has been completed before
driver's structures get freed from memory. This is especially
important as interrupts may keep arriving if the line is shared with
another PHY.
The solution is to ignore phy_interrupt() calls if the reported device
has already been halted and calling flush_scheduled_work() from
phy_stop_interrupts() (but guarded with current_is_keventd() in case
the function has been called through keventd from the MAC device's
close call to avoid a deadlock on the netlink lock).

The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv
with ATAPI devices on controllers running in ADMA mode. Some of the
logic in the nv_adma_bmdma_* functions was inverted causing a bunch of
warnings and caused those functions not to work properly. Also, when an
ATAPI device is connected, we need to use the legacy DMA engine. The
code now disables the PCI configuration register bits for ADMA so that
this works, and ensures that no ATAPI DMA commands go through until this
is done.

This patch updates the sata_promise driver as follows:
- Correct typo in definition of PDC_TBG_MODE: it's at 0x41C not 0x41
in first-generation chips. This error caused PCI access alignment
exceptions on SPARC64, and on all platforms it disabled the expected
initialisation of TBG mode.
- Add flags field to struct pdc_host_priv. Define PDC_FLAG_GEN_II
and use it to distinguish first- and second-generation chips.
- Prevent the FLASH_CTL FIFO_SHD bit from being set to 1 on second-
generation chips. This matches Promises' ulsata2 driver.
- Prevent TBG mode and SLEW rate initialisation in second-generation chips.
These two registers have moved, TBG mode has been redefined, and
Promise's ulsata2 driver no longer attempts to initialise them.
- Correct PCI device table so devices 0x3570, 0x3571, and 0x3d73 are
marked as 2057x (2nd gen) not 2037x (1st gen).
- Correct PCI device table so device 0x3d17 is marked as 40518
(2nd gen 4 ports) not 20319 (1st gen 4 ports).
- Correct pdc_ata_init_one() to treat 20771 as a second-generation chip.
Tested on 0x3d75 (2nd gen), 0x3d73 (2nd gen), and 0x3373 (1st gen) chips.
The information comes from the newly uploaded Promise SATA HW specs,
Promise's ultra and ulsata2 drivers, and debugging on 3d75/3d73/3373 chips.
hp->hotplug_offset could now be removed and its value recomputed
in pdc_host_init() using hp->flags, but that would be a cleanup
not a functional change, so I'm ignoring it for now.
