net: provide default_advmss() methods to blackhole dst_ops
Commit 0dbaee3b37e118a (net: Abstract default ADVMSS behind an
accessor.) introduced a possible crash in tcp_connect_init(), when
dst->default_advmss() is called from dst_metric_advmss()

Expand CONFIG_DEBUG_LIST to several other list operations
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..

enic: Always use single transmit and single receive hardware queues per device
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.

net: Add initial_ref arg to dst_alloc().
This allows avoiding multiple writes to the initial __refcnt.
The most simplest cases of wanting an initial reference of "1"
in ipv4 and ipv6 have been converted, the rest have been left
along and kept at the existing "0".
