* Don't initialize the card (and start an autonegotiation) every time the IP
address changes. Makes 'dhclient sk0' invocations way faster and more
consistant. i.e. one DHCPREQUEST elicits the DHCPACK.

doing that in bfe_stop().
This should fix a panic recently reported on -current occuring when taking
device down then up. In the original implementation, an "ifconfig bfe0 down"
triggers bfe_stop(), which also destroys all TX/RX descriptor dmamaps. Hence
the subsequent "ifconfig bfe0 up" would force the device to use those
already-released dmamap and thus panic the kernel.

Add sessrele() which does the proper cleanup and have SESSRELE() call it.
Use SESSRELE also in pgdelete().

fedisableexcept(), and fegetexcept(). These two sets of routines
provide the same functionality. I implemented the former as an
undocumented internal interface to make the regression test easier to
write. However, fe(enable|disable|get)except() is already part of
glibc, and I would like to avoid gratuitous differences. The only
major flaw in the glibc API is that there's no good way to report
errors on processors that don't support all the unmasked exceptions.
