be5740a255 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

334a01d995 Don't use the preprocessor while inside function-like macro
invocations as doing so violates the C specification. This
fixes the build with Clang.

4713c64cd8 - Change this driver to do taskqueue(9) based TX and interrupt
handling in order to reduce interrupt overhead which results in
  better performance.
- Call ether_ifdetach(9) before stopping the controller and the
  callouts detach in order to prevent active BPF listeners to clear
  promiscuous mode which may lead to the tick callout being restarted
  which will trigger a panic once it's actually gone.
- Add explicit IFF_DRV_RUNNING checking in order to prevent extra
  link up/down events when using dhclient(8).
- Use the correct macro for deciding whether 2/3 of the available TX
  descriptors are used.
- Wrap the RX fault printing in #ifdef CAS_DEBUG in order to not
  unnecessarily frighten users and as debugging was the actual
  intention. Real errors caused by these faults still will be
  accumulated as input errors. It might be a good idea to later on
  add driver specific counters for the faults though.

6c0f8373ed Add cas(4), a driver for Sun Cassini/Cassini+ and National Semiconductor
DP83065 Saturn Gigabit Ethernet controllers. These are the successors
of the Sun GEM controllers and still have a similar but extended transmit
logic. As such this driver is based on gem(4).
Thanks to marcel@ for providing a Sun Quad GigaSwift Ethernet UTP (QGE)
card which was vital for getting this driver to work on architectures
not using Open Firmware.
