The default Tx ring size for the sky2 driver is quite large and could
cause excess buffer bloat for many users. The minimum ring size
possible and still allow handling the worst case packet on 64bit platforms
is 38 which gets rounded up to a power of 2. But most packets only require
a couple of ring elements.

* when device was set to down, some IRQ bits left enabled so a

* quick link on Optima chip set was enabled without handler

ip6_tunnel: copy parms.name after register_netdevice
Commit 1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create
because register_netdevice will now create a valid name. This works for the
net_device itself.
However the tunnel keeps a copy of the name in the parms structure for the
ip6_tnl associated with the tunnel. parms.name is set by copying the net_device
name in ip6_tnl_dev_init_gen. That function is called from ip6_tnl_dev_init in
ip6_tnl_create, but it is done before register_netdevice is called so the name
is set to a bogus value in the parms.name structure.
This shows up if you do a simple tunnel add, followed by a tunnel show:
[root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200
[root@localhost ~]# ip -6 tunnel show
ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000)

also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.

This reverts commit 330605423ca6eafafb8dcc27502bce1c585d1b06.
The commit introduces regression when two 2.1 devices attempt
establish rfcomm channel. Such connection is refused since there's
a security block issue on l2cap. It means the link is unencrypted.

forcedeth: Improve stats counters
Rx byte count was off; instead use the hardware's count. Tx packet
count was counting pre-TSO packets; instead count on-the-wire packets.
Report hardware dropped frame count as rx_fifo_errors.
- The count of transmitted packets reported by the forcedeth driver
reports pre-TSO (TCP Segmentation Offload) packet counts and not the
count of the number of packets sent on the wire. This change fixes
the forcedeth driver to report the correct count. Fixed the code by
copying the count stored in the NIC H/W to the value reported by the
driver.
- Count rx_drop_frame errors as rx_fifo_errors:
We see a lot of rx_drop_frame errors if we disable the rx bottom-halves
for too long. Normally, rx_fifo_errors would be counted in this case.
The rx_drop_frame error count is private to forcedeth and is not
reported by ifconfig or sysfs. The rx_fifo_errors count is currently
unused in the forcedeth driver. It is reported by ifconfig as overruns.
This change reports rx_drop_frame errors as rx_fifo_errors.

forcedeth: remove unneeded stats updates
Function ndo_get_stats() updates most of the stats from hardware
registers, making the manual updates un-needed. This change removes
these manual updates. Main exception is rx_missed_errors which needs
manual update.
Another exception is rx_packets, still updated manually in this commit
to make sure this patch doesn't change behavior of driver. This will
be addressed by a future patch.

forcedeth: fix race when unloading module
When forcedeth module is unloaded, there exists a path that can lead
to mod_timer() after del_timer_sync(), causing an oops. This patch
short-circuits this unneeded path, which originates in
nv_get_ethtool_stats().
Tested:
x86_64 16-way + 3 ethtool -S infinite loops + 100Mbps incoming traffic
