o Instead of locking and unlocking all over the place, use
lock assertions to make certain that the bfe lock is held
where necessary.
o Create locked and unlocked versions of bfe_init and bfe_start. These
functions can be called from outside the module and by functions
within the bfe module. The calls from outside the module don't
hold the bfe lock so the unlocked versions called by these functions
simple obtain the bfe lock and call the locked version.
- Fix a typo (scp) in the locking macros that only worked because in all the
instances in which it was called the softc pointer happened to be named 'sc'.
- Mark the interrupt MPSAFE

or packet forwarding). There are more efficient ways to do this
but for now use the least intrusive approach.

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.
This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

written by Stuart Walsh and Duncan Barclay (with some kibbitzing by
me). I'm checking it in on Stuart's behalf.
The BCM4401 is built into several x86 laptop and desktop systems. For the
moment, I have only enabled it in the x86 kernel config because although
it's a PCI device, I haven't heard of any standalone NICs that use it. If
somebody knows of one, we can easily add it to the other arches.
This driver uses register/structure data gleaned from the Linux
driver released by Broadcom, but does not contain any of the code
from the Linux driver itself. It uses busdma.
