The following patches are going to break skb fragments into smaller
sizes. This patch attempts to make the change easier to digest by only
addressing the skb teardown portion.
The patch modifies the driver to skip over any BDs that have a flag set
that indicates the BD isn't the beginning of an skb fragment. Such BDs
were a result of segmentation and do not need a pci_unmap_page() call.

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

When these mailbox commands are processed by the FW and responses are sent,
unexpected events are received by other modules' FSMs (f.e. bfa_msgq) which
have not posted any mailbox commands after IOC was enabled.
