Since I cannot convince the lazy driver authors (hello Michael)
to stop (ab)using the MGMT interface type internally in their
drivers, this patch introduces a new _INVALID type especially
for their use and changes all affected drivers to use it.

As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses
udev by presenting 2 interfaces with the same MAC address. Also, at the time
of detection, the 'type' attribute is 1, identical to other hostap interfaces.
The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is
not set until after registration.
Setting it before register_netdev() is called allows us to avoid this
confusion. We can do this by propogating the HOSTAP_INTERFACE type through
to hostap_setup_dev().

This is a follow up to the patches from Denys Vlasenkos
<vda.linux@googlemail.com> to further optimize firmware loading.
1. In bnx2_init_cpus(), we allocate memory for decompression once
and use it repeatedly instead of doing this for every firmware image.
2. We eliminate the BSS and SBSS firmware sections in bnx2_fw*.h since
these are always zeros.

Hi,
this are the changes to the smc911x driver, which were necessary
to get it running on the Magic Panel R2 (smsc9115).
It is a SH3-DSP based board. The other patches are available on
the linuxsh-dev mailinglist.
http://marc.info/?l=linuxsh-dev&r=1&b=200708&w=2
It was necessary to set the irq sense to low level.
Therefor the SMC_IRQ_SENSE define was added.
How are the chances for inclusion in 2.6.24?

The existing OF glue code was crufty and broken. Rather than fix it, it
will be removed, and the ethernet driver now talks to the device tree
directly.
The old, non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM
platforms are dropped from arch/ppc (which will hopefully be soon), and
existing arch/powerpc boards that I wasn't able to test on for this
patchset get converted (which should be even sooner).

This patch modifies gzip unpacking code in bnx2 driver so that
it does not depend on bnx2 internals. I will move this code
out of the driver and into zlib in follow-on patch.
It can be useful in other drivers which need to store firmwares
or any other relatively big binary blobs - fonts, cursor bitmaps,
whatever.
Patch is run tested by Michael Chan (driver author).

Hook up the 93cx6 eeprom code to the ax88796 driver and modify the ax88796
driver to read out the mac address from the eeprom. We need this for the
ax88796 on certain SuperH boards. The pin configuration used to connect
the eeprom to the ax88796 on these boards is the same as pointed out by the
ax88796 datasheet, so we can probably reuse this code for multiple
platforms in the future.

Ensure the PHY_HALTED state is not entered with the IRQ asserted as it
could lead to an interrupt loop.
There is a small window in phy_stop(), where the state of the PHY machine
indicates it has been halted, but its interrupt output might still be
unmasked. If an interrupt goes active right at this moment it will loop as
the phy_interrupt() handler exits immediately with IRQ_NONE if the halted
state is seen. It is unsafe to extend the phydev spinlock to cover
phy_interrupt(). It is safe to swap the order of the actions though as all
the competing places to unmask the interrupt output of the PHY, which are
phy_change() and phy_timer() are already covered with the lock as is the
sequence in question.

Keep track of disable_irq_nosync() invocations and call enable_irq() the
right number of times if work has been cancelled that would include them.
Now that the call to flush_work_keventd() (problematic because of
rtnl_mutex being held) has been replaced by cancel_work_sync() another
issue has arisen and been left unresolved. As the MDIO bus cannot be
accessed from the interrupt context the PHY interrupt handler uses
disable_irq_nosync() to prevent from looping and schedules some work to be
done as a softirq, which, apart from handling the state change of the
originating PHY, is responsible for reenabling the interrupt. Now if the
interrupt line is shared by another device and a call to the softirq
handler has been cancelled, that call to enable_irq() never happens and the
other device cannot use its interrupt anymore as its stuck disabled.
I decided to use a counter rather than a flag because there may be more
than one call to phy_change() cancelled in the queue -- a real one and a
fake one triggered by free_irq() if DEBUG_SHIRQ is used, if nothing else.
Therefore because of its nesting property enable_irq() has to be called the
right number of times to match the number disable_irq_nosync() was called
and restore the original state. This DEBUG_SHIRQ feature is also the
reason why free_irq() has to be called before cancel_work_sync().
While at it I updated the comment about phy_stop_interrupts() being called
from `keventd' -- this is no longer relevant as the use of
cancel_work_sync() makes such an approach unnecessary. OTOH a similar
comment referring to flush_scheduled_work() in phy_stop() still applies as
using cancel_work_sync() there would be dangerous.
Checked with checkpatch.pl and at the run time (with and without
DEBUG_SHIRQ).

Use spin_lock_bh()/spin_unlock_bh() for the phydev lock throughout as it
is used in phy_timer() that is called as a softirq and all the other
operations may happen in the user context.
There has been a change recently that did such a conversion for some of the
operations on the lock, but some have been left intact. Many of them,
perhaps all, may be called in the user context and I was able to trigger
recursive spinlock acquisition indeed, so I think for the sake of long-term
maintenance it is best to convert them all, even if unnecessarily for one
or two -- better safe than sorry.
Perhaps one in phy_timer() could actually be skipped as only called as a
softirq -- I can send an update if that sounds like a good idea.
Checked with checkpatch.pl and at the runtime.
