Currently we set all skbs with CHECKSUM_UNNECESSARY, even
those whose protocol we don't know. This patch just
add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

At least one board using the FEC driver does not have a conventional
PHY attached to it, it is directly connected to a somewhat simple
ethernet switch (the board is the SnapGear/LITE, and the attached
4-port ethernet switch is a RealTek RTL8305). This switch does not
present the usual register interface of a PHY, it presents nothing.
So a PHY scan will find nothing - it finds ID's of 0 for each PHY
on the attached MII bus.
After the FEC driver was changed to use phylib for supporting PHYs
it no longer works on this particular board/switch setup.
Add code support to use a fixed phy if no PHY is found on the MII bus.
This is based on the way the cpmac.c driver solved this same problem.

commit 511d22247b (tg3: 64 bit stats on all arches), overlooked the
rx_dropped accounting.
We use a full "struct rtnl_link_stats64" to hold rx_dropped value, but
forgot to report it in tg3_get_stats64().
Use an "unsigned long" instead to shrink "struct tg3" by 176 bytes, and
report this value to stats readers.
Increment rx_dropped counter for oversized frames.

For carrier detection to work properly when binding the driver with a cable

Stanse found that i2400m_rx frees skb, but still uses skb->len even
though it has skb_len defined. So use skb_len properly in the code.
And also define it unsinged int rather than size_t to solve
compilation warnings.

with hardware slow in negotiation, the system did freeze
while trying to mount root on nfs at boot time.
the link state has not been initialised so network stack
tried to start transmission right away. this caused instant
retries, as the driver solely stated business upon link down,
rendering the system unusable.
notify carrier off initially to prevent transmission until
phylib will report link up.

bonding: Bond creation failed.
It happens because a user space writer to bond_master can try to
register an already existing bond interface name. Fix it by teaching
bond_create to check for the existance of devices with that name first
in cases where a non-NULL name parameter has been passed in

iwl3945's scan_completed calls into the mac80211 stack which triggers a
warn on if there is no scan outstanding.
This can be avoided by not calling scan_completed but abort_scan in
iwl3945_request_scan in the done: branch of the function which is used
as an error out.
The done: branch seems to be an error-out branch, as, for example, if
iwl_is_ready(priv) returns false the done: branch is executed.
NOTE:
I'm not familiar with the driver at all.
I just quickly scanned as a reaction to
https://bugzilla.kernel.org/show_bug.cgi?id=17722
the users of scan_completed in the iwl3945 driver and noted the odd
discrepancy between the comment above this instance and the comment in
mac80211 scan_completed function.
