Fallback on the local-mac-address prom property if the Cassini device
does not have an address programmed in the VPD ROM. This uses the same
technique as implemented by the sungem driver.
The problem was reported by Frans van Berckel using Debian kernel 2.6.34-7
on Sun Fire V440. udev was assigning a new eth<n> device name on each reboot
because the cassini driver was using a random MAC address.
Fix tested on 2.6.34-7 and 2.6.37 Sun Fire V440. Compile tested against
2.6.36 davem/sparc-2.6.git

Event though with the above commit we obtain the configured DTIM period

* Preventing association with broken AP's
* Adds latency in roaming
So its better to always use the safe value of '1' for dtim period

Commit 3f5a2a713a zeroes out the statistics
message block (SMB) and coalescing message block (CMB) when adapter ring
resources are freed. This is desirable behavior, but, as a side effect,
the commit leads to an oops when atl1_set_ringparam() attempts to alter
the number of rx or tx elements in the ring buffer (by using ethtool
-G, for example). We don't want SMB or CMB to change during this
operation.
Modify atl1_set_ringparam() to preserve SMB and CMB when changing ring
parameters.

This implements 64 bit statistics support and fixes races when reading
counter values. The PHY counters can only be accessed 16 bits at a time,
so they are subject to carry races.
NB:
* TX/RX counters are maintained in software because the the hardware packet count
is only a 32 bit value.
* Error counters are really only 32 bit.
* Old 32 bit counter fields in dev->stats still used for some
software counters

Commit 56543af "starfire: use BUILD_BUG_ON for netdrv_addr_t" revealed
that the preprocessor condition used to find the size of dma_addr_t
yielded the wrong result for some architectures and configurations.
This was kluged for 64-bit PowerPC in commit 3e502e6 by adding yet
another case to the condition. However, 64-bit MIPS configurations
are not detected reliably either.
This should be fixed by using CONFIG_ARCH_DMA_ADDR_T_64BIT, but that

The sky2 driver uses the legacy PCI power management, so it has to do
some PCI-specific things in its ->suspend() and ->resume() callbacks,
which isn't necessary and should better be done by the PCI
sybsystem-level power management code. Moreover, it uses
device_set_wakeup_enable() incorrectly (that function should be
used when the WoL setting is changed rather than during suspend).
Convert sky2 to the new PCI power management framework and make it

When changing ring size, we free all memory including status block
memory. If we're in INTA mode and sharing IRQ, the IRQ handler can
be called and it will reference the NULL status block pointer.
Because of the lockless design of the IRQ handler, there is no simple
way to synchronize and prevent this. So we avoid this problem by
freeing the IRQ handler before freeing the status block memory.

Linux would not connect to other router running old version Cisco IOS (12.0).
This is most likely a bug in that version of IOS, since it is fixed
in later versions. As a workaround this patch allows a module parameter
to be set to disable compressing the protocol ID.
See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979
RFC 1990 allows an implementation to formulate MP fragments as if protocol
compression had been negotiated. This allows us to always send compressed
protocol IDs. But some implementations don't accept MP fragments with
compressed protocol IDs. This parameter allows us to interoperate with
them. The default value of the configurable parameter is the same as the
current behavior: protocol compression is enabled. If protocol compression
is disabled we will not send compressed protocol IDs.
This is based on an earlier patch by Bob Gilligan (using a sysctl).
Module parameter is writable to allow for enabling even if ppp
is already loaded for other uses.
