is a workaround for non-symetric teardown of the file systems at
shutdown with respect to the mount order at boot. The proper long term
fix is to properly detach devfs from the root mount before unmounting
each, and should be implemented, but since the problem is non-harmful,
this temporary band-aid will prevent false positive bug reports and
unnecessary error output for 6.0-RELEASE.

sizeof(struct g_eli_metadata) will return the exact number of bytes needed
for storing it on the disk.
Without this change GELI was unusable on amd64 (and probably other 64-bit
archs), because sizeof(struct g_eli_metadata) was greater than 512 bytes
and geli(8) was failing on assertion.

Instead, a list of attribute names is returned, where each

- Remove a lot of superfluous locking during attach. There is no need
to lock access to the driver until some other thread has a way of getting
to it. For ethernet drivers the other ways include registering an
interrupt handler via bus_setup_intr(), calling ether_ifattach() to hook
into the network stack, and kicking off a callout-driven timer via
callout_reset().
- Use callout_* rather than timeout/untimeout.
- Break out of xl_rxeof() if IFF_DRV_RUNNING is clear after ifp->if_input
returns to handle the case where the interface was stopped while we were
passing a packet up the stack. Don't call xl_rxeof() in xl_rxeof_task()
unless IFF_DRV_RUNNING is set. With these fixes in place, any
outstanding task will gracefully terminate as soon as it gets a chance to
run after the interface has been stopped via xl_stop(). As a result,
taskqueue_drain() is no longer required in xl_stop(). The task is still
drained in detach() however to make sure that detach() can safely destroy
the driver mutex at the end of the function.
- Lock the driver lock in the ifmedia callouts and don't lock across
ifmedia_ioctl() in xl_ioctl().
Note: glebius came up with most of (3) as well independently. I took a
rather roundabout way of arriving at the same conclusion.

researched by glebius, and incorporated by ISC into the next
version of BIND. Unfortunately, it looks like their release
will come after the release of FreeBSD 6, so we will bring
this in now.
The patch addresses a problem with high-load resolvers which
hit memory barriers. Without this patch, running the resolving
name server out of memory would lead to "unpredictable results."
Of course, the canonical answer to this problem is to put more
memory into the system, however that is not always possible, and
the code should be able to handle this situation gracefully in
any case.
struct ifnet most of if_findindex() become a complex no-op. Remove it
and replace it with a corrected version of the four line for loop it
devolved to plus some error handling. This should probably be replaced
with subr_unit at some point.
Switch from checking ifaddr_byindex to ifnet_byindex when looking for
empty indexes. Since we're doing this from if_alloc/if_free, we can
only be sure that ifnet_byindex will be correct. This fixes panics when
loading the ef(4) module. The panics were caused by the fact that
if_alloc was called four time before if_attach was called and thus
ifaddr_byindex was not set and the same unit was allocated again. This
in turn caused the first if_attach to fail because the ifp was not the
one in ifnet_byindex(ifp->if_index).
