the TOE for LAN operation. It is possible to set this to other values
(cluster for networks with little loss and really tight RTTs, and wan
for relatively large RTTs and/or lossy networks) depending on the
environment in which the TOE is being used.
None of this affects plain NIC operation in any way.

resources are partitioned.
- Reduce the number of virtual interfaces reserved for PF4. This leaves
spare room in the source MAC table and allows the driver to setup
filters that rewrite the source MAC address.
- Reduce the number of filters and use the freed up space for the CLIP
(Compressed Local IPv6 addresses) table. This is a prerequisite for
IPv6 TOE support which will follow separately in a series of commits.

- Device configuration via plain text config file. Also able to operate
when not attached to the chip as the master driver.
- Generic "work request" queue that serves as the base for both ctrl and
ofld tx queues.
- Generic interrupt handler routine that can process any event on any
kind of ingress queue (via a dispatch table).
- A couple of new driver ioctls. cxgbetool can now install a firmware
to the card ("loadfw" command) and can read the card's memory
("memdump" and "tcb" commands).
- Lots of assorted information within dev.t4nex.X.misc.* This is
primarily for debugging and won't show up in sysctl -a.
- Code to manage the L2 tables on the chip.
- Updates to cxgbe(4) man page to go with the tunables that have changed.
- Updates to the shared code in common/
- Updates to the driver-firmware interface (now at fw 1.4.16.0)
