8820ce5fe7 T4 packet filtering/steering.
- Enable 5-tuple and every-packet lookup.

- Setup the default filter mode to allow filtering/steering based on IP
  protocol, ingress port, inner VLAN ID, IP frag, FCoE, and MPS match
  type; all combined together.  You can also filter based on MAC index,
  Ethernet type, IP TOS/IPv6 Traffic Class, and outer VLAN ID but you'll
  have to modify the default filter mode and exclude some of the
  match-fields in it.

  IPv4 and IPv6 SIP/DIP/SPORT/DPORT are always available in all filter
  rules.

- Add driver ioctls to get/set the global filter mode.

- Add driver ioctls to program and delete hardware filters.  A couple of
  the "switch" actions that rewrite Ethernet and VLAN information and
  switch the packet out of another port may not work as the L2 code is not
  yet in place.  Everything else, including all "drop" and "pass" rules
  with RSS or absolute qid, should work.

f7dfe243b4 - Move all Ethernet specific items from sge_eq to sge_txq. sge_eq is
now a suitable base for all kinds of egress queues.

- Add control queues (sge_ctrlq) and allocate one of these per hardware
  channel.  They can be used to program filters and steer traffic (and
  more).

2be67d2948 Fix a couple of bad races that can occur when a cxgbe interface is taken
down.  The ingress queue lock was unused and has been removed as part of
these changes.

- An in-flight egress update from the SGE must be handled before the
  queue that requested it is destroyed.  Wait for the update to arrive.

- Interrupt handlers must stop processing rx events for a queue before
  the queue is destroyed.  Events that have not yet been processed
  should be ignored once the queue disappears.

pending.

a91fea93ad Do not over-allocate MSI interrupts for the case where each ingress
queue has its own interrupt.  If the exact number that we need is not a
power of 2 and we're using MSI, then switch to interrupt multiplexing.

While here, replace the magic numbers with something more readable.
