In the following patches, the process the driver will use to assign skb
fragments to transmit BDs will get more complicated.  To prepare for
that new code, this patch seeks to simplify how transmit BDs are
populated.  It does this by separating the code that assigns the BD
members from the logic that controls how the fields are set.

The AX88772B uses only 11 bits of the header for the actual size. The other bits
are used for something else. This causes dmesg full of messages:

	asix_rx_fixup() Bad Header Length

This patch trims the check to only 11 bits. I believe on older chips, the
remaining 5 top bits are unused.

I noticed that you took some time back in late 2009 to 'consolidate' the
split format-strings present in the bonding driver at the time and I've
decided I'm fine to leave them the way they are.  The main point of my
patch was to change the output and I would like to get that included.
Here is my updated patch...

Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init

Many are using sysfs to configure bonding rather than module options, so
there is no need for bonding to throw this warning in normal cases.

Keep the message around when debugging is enabled as it might be useful
for someone desperate enough to enable debugging, but eliminate it
otherwise.

When a bond contains a device where one name is the subset of another
(eth1 and eth10, for example), one cannot properly set the primary
device or the currently active device.

This was reported and based on work by Takuma Umeya.  I also verified
the problem and tested that this fix resolves it.

V2: A few did not like the the current code or my changes, so I
refactored bonding_store_primary and bonding_store_active_slave to be a
bit cleaner, dropped the use of strnicmp since we did not really need
the comparison to be case insensitive, and formatted the input string
from sysfs so a comparison to IFNAMSIZ could be used.

I also discovered an error in bonding_store_active_slave that would
modify bond->primary_slave rather than bond->curr_active_slave before
forcing the bonding driver to choose a new active slave.

V3: Actually sending the proper patch....

After the last patch, We are left in a state in which only drivers calling
ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real
hardware call ether_setup for their net_devices and don't hold any state in
their skbs.  There are a handful of drivers that violate this assumption of
course, and need to be fixed up.  This patch identifies those drivers, and marks
them as not being able to support the safe transmission of skbs by clearning the
IFF_TX_SKB_SHARING flag in priv_flags

Pktgen attempts to transmit shared skbs to net devices, which can't be used by
some drivers as they keep state information in skbs.  This patch adds a flag
marking drivers as being able to handle shared skbs in their tx path.  Drivers
are defaulted to being unable to do so, but calling ether_setup enables this
flag, as 90% of the drivers calling ether_setup touch real hardware and can
handle shared skbs.  A subsequent patch will audit drivers to ensure that the
flag is set properly

|   No need for matching code in addrconf_leave_anycast() as it

After analysis, because 1) we may add two or more prefixes on the
same interface, or 2)user may have manually joined that anycast,
we may hit chances to have anycast address which as if we had
generated one by /127 prefix and we should not leave from subnet-
