4dba21f17e L2 table code. This is enough to get the T4's switch + L2 rewrite
filters working.  (All other filters - switch without L2 info rewrite,
steer, and drop - were already fully-functional).

Some contrived examples of "switch" filters with L2 rewriting:

# cxgbetool t4nex0  iport 0  dport 80  action switch  vlan +9  eport 3
Intercept all packets received on physical port 0 with TCP port 80 as
destination, insert a vlan tag with VID 9, and send them out of port 3.

# cxgbetool t4nex0  sip 192.168.1.1/32  ivlan 5  action switch \
	vlan =9  smac aa:bb:cc:dd:ee:ff  eport 0
Intercept all packets (received on any port) with source IP address
192.168.1.1 and VLAN id 5, rewrite the VLAN id to 9, rewrite source mac
to aa:bb:cc:dd:ee:ff, and send it out of port 0.

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.
