done in ixgbe, thanks to Mike Karels for this fix. When exiting
promiscuous mode MPE bit was being unconditionally cleared, this
should not be done if we are in MAX multicast groups.
Allow boothowto and bootverbose to be set via kernel options, which
is useful on architectures that are unable to rely on a boot loader
to pass configuration variables to the kernel.

in the pagedep and inodedep hash tables. An entry in the table is
skipped because 'pagedep_hash' and 'inodedep_hash' hold the size
of the hash tables - 1.
The chance that this would have any operational failure is extremely
unlikely. These funtions only need to find a single entry and are
only called when there are too many entries. The chance that they
would fail because all the entries are on the single skipped hash
chain are remote.

different ATA channels, required for acard and pc98 ATA controllers, block
access to second channels of both, hoping that one working channel is better
then none. I have an idea how that support could be implemented, but I have
no hardware to work on that.

Prior to r248571 spa_open was always called with a bare pool name,
but now it is called with a dataset name instead (spa_lookup handles
that).
So, when a ZFS root is mounted spa_open is called with a name of a root
dataset, which can very well be different from the pool name.
But zvol_create_minors should be called with the pool name, because it
performs a recursive traversal of all datasets under the name to find
all those that are volumes.

central place, like it was done in the i915 driver.

vm_radix_lookup{,_ge,_le}(), and vm_radix_remove().
Simplify the control flow of vm_radix_lookup_{ge,le}().

Right now it's in the TDMA code and I can live with that; but it really
should get fixed.
I'll do a more thorough audit of this code soon.
* Don't use BUS_DMA_ALLOCNOW for descriptor DMA maps; we never use
bounce buffers for the descriptors themselves.
* Add some XXX's to mark where the ath_buf has its mbuf ripped from
underneath it without actually cleaning up the dmamap. I haven't
audited those particular code paths to see if the DMA map is guaranteed
to be setup there; I'll do that later.
* Print out a warning if the descdma tidyup code is given some descriptors
w/ maps to free. Ideally the owner will free the mbufs and unmap
the descriptors before freeing the descriptor/ath_buf pairs, but
right now that's not guaranteed to be done.

extattr_set_{fd,file,link} is logically a write(2)-like operation and
should return ssize_t, just like extattr_get_*. Also, the user-space
utility was using an int for the return value of extattr_get_* and
extattr_list_*, both of which return an ssize_t.

the buffer is being freed.
* When buffers are cloned, the original mapping isn't copied but it
wasn't freeing the mapping until later. To be safe, free the
mapping when the buffer is cloned.
* ath_freebuf() now no longer calls the busdma sync/unmap routines.
* ath_tx_freebuf() now calls sync/unmap.
* Call sync first, before calling unmap.
Tested:
* AR5416, STA mode
The normal RX path (ath_rx_pkt()) will sync and unmap the
buffer before passing it up the stack. We only need to do this
if we're flushing the FIFO during reset/shutdown.
Merge change from illumos:
1368 enablings on defunct providers prevent providers from unregistering
We try to address some underlying differences between the Solaris
and FreeBSD implementations: dtrace_attach() / dtrace_detach() are
currently unimplemented in FreeBSD but the new code from illumos
makes use of taskq so some adaptations were made to dtrace_open()
and dtrace_close() to handle them appropriately.

uart(4) allocates send and receiver buffers in attach() before it calls
the low-level driver's attach routine. Many low-level drivers set the
fifo sizes in their attach routine, which is too late. Other drivers set
them in the probe() routine, so that they're available when uart(4)
allocates buffers. This fixes the ones that were setting the values too
late by moving the code to probe().
