'-n' to tell the driver to create _up to_ 'n' queues if enough cores are
available. For example, setting hw.cxgbe.nrxq10g="-32" will result in
16 queues if the system has 16 cores, 32 if it has 32.
There is no change in the default number of queues of any type.

undo_offload_socket() is only called by t4_connect() during a connection
setup failure, but t4_connect() still owns the TOE PCB and frees ita
after undo_offload_socket() returns. Release a reference in
undo_offload_socket() resulted in a double-free which panicked when
t4_connect() performed the second free. The reference release was
added to undo_offload_socket() incorrectly in r299210.

Active Open:
- Save the socket's vnet at the time of the active open (t4_connect) and
switch to it when processing the reply (do_act_open_rpl or
do_act_establish).
Passive Open:
- Save the listening socket's vnet in the driver's listen_ctx and switch
to it when processing incoming SYNs for the socket.
- Reject SYNs that arrive on an ifnet that's not in the same vnet as the
listening socket.
CLIP (Compressed Local IPv6) table:
- Add only those IPv6 addresses to the CLIP that are in a vnet
associated with one of the card's ifnets.
Misc:
- Set vnet from the toepcb when processing TCP state transitions.
- The kernel sets the vnet when calling the driver's output routine
so t4_push_frames runs in proper vnet context already. One exception
is when incoming credits trigger tx within the driver's ithread. Set
the vnet explicitly in do_fw4_ack for that case.

a linuxkpi style device is expected. If OFED/linuxkpi actually starts
using this field then we'll have to figure out whether to create fake
devices for these drivers or have linuxkpi deal with NULL device.

There are 4 independent knobs in T5+ chips to include or exclude PAUSE
frames from the "total frames" and "multicast frames" counters in either
direction. This change lets the driver deal with any combination of
these settings.
contiguous regions in an mbuf chain.
If the payload of an mbuf ends at a page boundary count_mbuf_nsegs would
incorrectly consider the next mbuf's payload physically contiguous based
solely on a KVA comparison.

come up as 't6nex' nexus devices with 'cc' ports hanging off them.
The T6 firmware and configuration files will be added as soon as they
are released. For now the driver will try to work with whatever
firmware and configuration is on the card's flash.
