The id_table field of the struct usb_device_id is constant in <linux/usb.h>

The ISA skeleton net driver has been obsolete and unmaintained for many

look much more like a PCI driver, and make much better use of netdev

Quick fix for memory/module refcount leak.
Reference count of listener instance never reaches 0.

Start/stop of ulogd2 is enough to trigger this bug!

Now, refcounting there looks very fishy in particular this code:

 	if (!try_module_get(THIS_MODULE)) {
		...

and creation of listener instance with refcount 2,
so it may very well be ripped and redone.  :-)

Clients will set their MTU to 1280 if they receive a
ICMPV6_PKT_TOOBIG message with an MTU less than 1280.

To allow encapsulating of packets over a 1280 link
we should always accept packets with a size of 1280
for forwarding even if the path has a lower MTU and
fragment the encapsulated packets afterwards.

In case a forwarded packet is not going to be encapsulated
a ICMPV6_PKT_TOOBIG msg will still be send by ip6_fragment()
with the correct MTU.

Disabling TSO can cause the dev_watchdog timer to be triggered because
when TSO is disabled netif_tx_stop_all_queues is called.  If the watchdog
timer fires while the queues are stopped and traffic has not recently been
sent on a paticular queue this is falsly identified as a hang and
ndo_tx_timeout() is called.  This is ocossionally seen during testing.

This removes the netif_tx_stop_all_queues() it is not needed.  The scheduler
submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and
if so it calls dev_gso_segment.  Disabling TSO will cause dev_hard_start_xmit()
to do the gso processing.   However ixgbe does not use the features flags to
determine if it needs to use tso or not instead it uses skb->gso_size so
ixgbe will process these frames correctly regardless of the netdev features
flag.

The netif_wake_queue() is called correctly (i.e. only on !txfull
