It is wrong to destroy a bonding master from a context that uses the sysfs
of that bond. When last IPoIB slave is unenslaved from by writing to a
sysfs file (for bond0 this would be /sys/class/net/bond0/bonding/slaves)
the driver tries to destroy the bond. This is wrong and can lead to a
lockup or a crash. This fix lets the bonding master stay and relies on
the user to destroy the bonding master if necessary (i.e. before module
ib_ipoib is unloaded)
This patch affects only bonds of IPoIB slaves. Ethernet slaves stay
unaffected.

Refactor mii monitor. As with the previous ARP monitor refactor,
the motivation for this is to handle locking rationally (in this case,
removing conditional locking) and generally clean up the code.
This patch breaks up the monolithic mii monitor into two phases:
an inspection phase, followed by an optional commit phase. The commit phase
is the only portion that requires RTNL or makes changes to state, and is
only called when inspection finds something to change.

Some hardware set promisc when they are requested to set IFF_ALLMULTI flag.
It's ok, but if drivers set IFF_PROMISC flag when they set promisc,
it will broken upper layer handle for promisc and allmulti.
In addition, drivers can use their own hardware programming to make it.
So do not allow drivers to set IFF_* flags.
This is a general driver fix, so I didn't split it to pieces and send
to specific driver maintainers.

The dm9000 driver reads the chip's MAC address from the attached EEPROM. When
no EEPROM is present, or when the MAC address is invalid, it falls back to
reading the address from the chip.
This patch lets platform code set the desired MAC address through platform
data.

Fix possible bug where end of receive buffer could be overwritten.
The allocation needs to allow for the reserved space. This would only happen
if device received packet greater than Ethernet standard MTU.
Change this driver to use netdev_alloc_skb rather than setting skb->dev
directly. For the initial allocation it doesn't need to be GFP_ATOMIC.

The L1 hardware contains a bug that flags a fragmented IP packet
as having an incorrect TCP/UDP checksum, even though the packet
is perfectly valid and its checksum is correct. There's no way to
distinguish between one of these good packets and a packet that
actually contains a TCP/UDP checksum error, so all we can do is
allow the packet to be handed up to the higher layers and let it
be sorted out there.
Add a comment describing this condition and remove the code that
currently fails to handle what may or may not be a checksum error.

This re-introduces commit 2b14290078,
which was reverted due to the regression it caused by commit
fca082c9f1.
That regression was not root-caused by the original commit, it was just
uncovered by it, and the real fix was done by Alan Stern in commit
580da34847 ("Fix USB storage hang on
command abort").
We can thus re-introduce the change that was confirmed by Alan Jenkins
to be still required by his odd card reader.
