In preparation of giving mii_bus objects a device tree presence of
their own, rename struct mii_bus's ->dev argument to ->parent, since
having a 'struct device *dev' that points to our parent device
conflicts with introducing a 'struct device dev' representing our own
device.

Remove the EXPERIMENTAL label from the atl1 driver and change the vendor
name to include Attansic's successor, Atheros. We'll leave Attansic in
the name since Attansic's PCI ID (1969) is encoded in the PCI config and
is what users encounter on their systems.

When NETIF_F_LLTX is set, the atlx driver will use a private lock.
But in recent kernels this implementation seems redundant and
can cause problems where AF_PACKET sees things twice. Since
NETIF_F_LLTX is marked as deprecated and shouldn't be used in
new driver, this patch removes NETIF_F_LLTX and adds a mmiowb
before sending packet. I have tested this driver on a Eee PC.
It works well.

The PHY's aneg is configured and restarted whenever the link is brought up,
e.g. when DHCP is started after the kernel has booted. This can take the
link down for several seconds while auto-negotiation is redone.
If the advertised features haven't changed, then it shouldn't be necessary
to bring down the link and start auto-negotiation over again.
genphy_config_advert() is enhanced to return 0 when the advertised features
haven't been changed and >0 when they have been.
genphy_config_aneg() then uses this information to not call
genphy_restart_aneg() if there has been no change.

The gabs array in the sctp_tsnmap structure is only used
in one place, sctp_make_sack(). As such, carrying the
array around in the sctp_tsnmap and thus directly in
the sctp_association is rather pointless since most
of the time it's just taking up space. Now, let
sctp_make_sack create and populate it and then throw
it away when it's done.

The tsn map currently use is 4K large and is stuck inside
the sctp_association structure making memory references REALLY
expensive. What we really need is at most 4K worth of bits
so the biggest map we would have is 512 bytes. Also, the
map is only really usefull when we have gaps to store and
report. As such, starting with minimal map of say 32 TSNs (bits)
should be enough for normal low-loss operations. We can grow
the map by some multiple of 32 along with some extra room any
time we receive the TSN which would put us outside of the map
boundry. As we close gaps, we can shift the map to rebase
it on the latest TSN we've seen. This saves 4088 bytes per
association just in the map alone along savings from the now
unnecessary structure members.

I noticed sysctl_local_port_range[] and its associated seqlock
sysctl_local_port_range_lock were on separate cache lines.
Moreover, sysctl_local_port_range[] was close to unrelated
variables, highly modified, leading to cache misses.
Moving these two variables in a structure can help data
locality and moving this structure to read_mostly section
helps sharing of this data among cpus.
Cleanup of extern declarations (moved in include file where
they belong), and use of inet_get_local_port_range()
accessor instead of direct access to ports values.

Current UDP port allocation is suboptimal.
We select the shortest chain to chose a port (out of 512)
that will hash in this shortest chain.
First, it can lead to give not so ramdom ports and ease
give attackers more opportunities to break the system.
Second, it can consume a lot of CPU to scan all table
in order to find the shortest chain.
Third, in some pathological cases we can fail to find
a free port even if they are plenty of them.
This patch zap the search for a short chain and only
use one random seed. Problem of getting long chains
should be addressed in another way, since we can
obtain long chains with non random ports.

While looking for some common code I came across difference
in checksum calculation between tcp_v6_send_(reset|ack) I
couldn't explain. I checked both v4 and v6 and found out that
both seem to have the same "feature". I couldn't find anything
in rfc nor anywhere else which would state that md5 option
should be ignored like it was in case of reset so I came to
a conclusion that this is probably a genuine bug. I suspect
that addition of md5 just was fooled by the excessive
copy-paste code in those functions and the reset part was
never tested well enough to find out the problem.
