The per-port mv643xx_eth_private struct had a private instance
of struct net_device_stats that was never ever written to, only
read (via the ethtool statistics interface). This patch gets
rid of the private instance, and tweaks the ethtool statistics
code in mv643xx_eth to use the statistics in struct net_device
instead.

A bunch of places in the mv643xx_eth driver use the 'mv643xx_'
prefix. Since the mv643xx is a chip that includes more than just
ethernet, this patch makes all those places use either no prefix
(for some internal-use-only functions), or the full 'mv643xx_eth_'
prefix.

The fact that mv643xx_eth is an ethernet driver is pretty obvious,

On 5761 non-e devices, two problems prevent the administrator from
overriding the WOL settings in the device's NVRAM.
The first problem is that GPIO 0 and GPIO 2 have been swapped. This
change prevented the administrator from turning on WOL when it is
disabled in NVRAM. The fix is to add a new path for the 5761 that
swaps the two GPIOs in the code as well.
The second problem is that GPIO 1 could not be toggled by the driver
because the GPIO is shared with the debug UART GPIO. This will prevent
the administrator from being able to turn WOL off if it was enabled in
NVRAM. The fix is to always disable the debug UART after a GRC reset.

The git commit ef167e2703 entitled
"Fix supporting flowctrl code" introduced a bug that prevents 5714S,
5715S and 5780S devices from falling back to a forced link mode. The
problem is that the added flow control check will always fail if flow
control is set to autoneg and either RX or TX (or both) flow control
is enabled. The driver defaults to setting flow control to autoneg
and advertises both RX and TX flow control.
The fix is to remove the errant check.

This fixes an issus that made "iwconfig eth1 power on" non-working.
When we get a "PS sleep" event, we have to confirm this to the firmware.
The confirm happens with a command, but this command is special: the
firmware won't send us a response. if_cs_host_to_card() is setting
priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and
was never cleared back.
Now I put the special knowledge that the CMD_802_11_PS_MODE with
CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly
clearing the dnld_sent state in lbs_send_confirmsleep().

When another scan is in progress, a direct scan gets dropped on the
floor. However, that direct scan is usually the scan that's really
needed by userspace, and gets stomped on by all the broadcast scans the
ipw2200 driver issues internally. Make sure the direct scan happens
eventually, and as a bonus ensure that the passive scan worker is
cleaned up when appropriate.
The change of request_passive_scan form a struct work to struct
delayed_work is only to make the set_wx_scan() code a bit simpler, it's
still only used with a delay of 0 to match previous behavior.

Some problems have been experienced in the field which cause an oops
in the pppol2tp driver if L2TP tunnels fail while passing data.
The pppol2tp driver uses private data that is referenced via the
sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes
sure that the driver uses sock_hold() when it holds a reference to the
sk pointer. This affects its sendmsg(), recvmsg(), getname(),
[gs]etsockopt() and ioctl() handlers.
Tested by ISP where problem was seen. System has been up 10 days with
no oops since running this patch. Without the patch, an oops would
occur every 1-2 days.

If there are no networks on the free list, expire the oldest one when
creating a new adhoc network. Because ipw2200 and the ieee80211 stack
don't actually cull old networks and place them back on the free list
unless they are needed for new probe responses, over time the free list
would become empty and creating an adhoc network would fail due to the !
