Strip them off in the driver. The VLAN Tag to be stripped will be given to the host

commit 5fa782c2f5 re-worked the
handling of unknown parameters. sctp_init_cause_fixed() can now
return -ENOSPC if there is not enough tailroom in the error
chunk skb. When this happens, the error header is not appended to
the error chunk. In that case, the payload of the unknown parameter
should not be appended either.

Eric W. Biederman reported a lockdep splat in inet_twsk_deschedule()
This is caused by inet_twsk_purge(), run from process context,
and commit 575f4cd5a5 (net: Use rcu lookups in inet_twsk_purge.)
removed the BH disabling that was necessary.
Add the BH disabling but fine grained, right before calling
inet_twsk_deschedule(), instead of whole function.

Eric W. Biderman and Michal Hocko reported various memory corruptions
that we suspected to be related to a LIST head located on stack, that
was manipulated after thread left function frame (and eventually exited,
so its stack was freed and reused).
Eric Dumazet suggested the problem was probably coming from commit
443457242b (net: factorize
sync-rcu call in unregister_netdevice_many)
This patch fixes __dev_close() and dev_close() to properly deinit their
respective LIST_HEAD(single) before exiting.

When list debugging is enabled, we aim to readably show list corruption
errors, and the basic list_add/list_del operations end up having extra
debugging code in them to do some basic validation of the list entries.
However, "list_del_init()" and "list_move[_tail]()" ended up avoiding
the debug code due to how they were written. This fixes that.
So the _next_ time we have list_move() problems with stale list entries,
we'll hopefully have an easier time finding them..

We believe that our earlier patch for supporting multiple hardware
receive queues per enic device requires more internal testing. At this
point, we think that it's best to disable the use of multiple receive
queues. The current patch provides an effective means for the same.
Also, we continue to disallow multiple hardware transmit queues per
device. But change the way we enforce this in order to maintain
consistency with the way receive queues are handled.

GCC emits all kinds of crazy zero extensions when we go from signed
int, to unsigned short, etc. etc.
This transformation has to be legal because:
1) In tkey_extract_bits() in mask_pfx(), the values are used to
perform shifts, on which negative values are undefined by C.
2) In fib_table_lookup() we perform comparisons with unsigned
values, constants, and additions. None of which should
encounter negative values.
