With r206844, CSUM_TCP is also set for CSUM_TSO case. Modify
drivers to take into account for the change. Basically CSUM_TSO
should be checked before checking CSUM_TCP.
Add driver for Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet.
This driver was written by Alexander Pohoyda and greatly enhanced
by Nikolay Denev. I don't have these hardwares but this driver was
tested by Nikolay Denev and xclin.
Because SiS didn't release data sheet for this controller, programming
information came from Linux driver and OpenSolaris. Unlike other open
source driver for SiS190/191, sge(4) takes full advantage of TX/RX
checksum offloading and does not require additional copy operation in
RX handler.
The controller seems to have advanced offloading features like VLAN
hardware tag insertion/stripping, TCP segmentation offload(TSO) as
well as jumbo frame support but these features are not available
yet. Special thanks to xclin <xclin<> cs dot nctu dot edu dot tw>
who sent fix for receiving VLAN oversized frames.
Fix ddb(4) "show geom addr" command when INVARIANTS is enabled. Don't
assert that the topology lock is held when g_valid_obj() is called from
debugger.
Make sure that we free the passed in data message if we don't actually
insert it onto the queue. Also, fix a mtx leak if someone turns off
devctl while we're processing a messages.

Avoid extraneous recovery cycles in the experimental NFS client
when an NFSv4 server reboots, by doing two things.
1 - Make the function that acquires a stateid for I/O operations
block until recovery is complete, so that it doesn't acquire
out of date stateids.
2 - Only allow a recovery once every 1/2 of a lease duration, since
the NFSv4 server must provide a recovery grace period of at
least a lease duration. This should avoid recoveries caused
by an out of date stateid that was acquired for an I/O op.
just before a recovery cycle started.
Put gone device timer into a structure tag that can hold more than 32 seconds. Oops.
Untangle some of the confusion about what role means when it's in the FCPARAM/SDPARAM
or isp_fc/isp_spi structures. This fixed a problem about seeing targets appear if you've
turned off autologin and find them, or rather don't, via camcontrol rescan.
- Introduce a blessed list for sxlocks that prevents the deadlkres to
panic on those ones. Populate this list with getblk and so_snd_sx and
so_rcv_sx.
- Fix ticks counter wrap-up

Change how multipath labels are created and managed. This makes it easier
to support various storage boxes which really aren't active-active.
We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.
A usage implication is that you should specificy the currently active
storage path as the first provider.
Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).

- Style fixes.

There's no need for checking result of M_WAITOK allocation.
The experimental NFS client was not filling in recovery credentials
for opens done locally in the client when a delegation for the file
was held. This could cause the client to crash in crsetgroups() when
recovering from a server crash/reboot. This patch fills in the
recovery credentials for this case, in order to avoid the client crash.
Also, add KASSERT()s to the credential copy functions, to catch any
other cases where the credentials aren't filled in correctly.

Plug reference leaks in the link-layer code ("new-arp") that previously
prevented the link-layer entry from being freed.
In both in.c and in6.c (though that code path seems to be basically dead)
plug a reference leak in case of a pending callout being drained.
In if_ether.c consistently add a reference before resetting the callout
and in case we canceled a pending one remove the reference for that.
In the final case in arptimer, before freeing the expired entry, remove
the reference again and explicitly call callout_stop() to clear the active
flag.
In nd6.c:nd6_free() we are only ever called from the callout function and
thus need to remove the reference there as well before calling into
llentry_free().
In if_llatbl.c when freeing the entire tables make sure that in case we
cancel a pending callout to remove the reference as well.

In if_detach_internal() we cannot hold the af_data lock over the
dom_ifdetach() calls as they might sleep for callout_drain().
Do as we do in if_attachdomain1() [r121470] and handle
if_afdata_initialized earlier and call dom_ifdetach() unlocked.
Discussed with: rwatson
In if_detach_internal() only try to do the detach run if if_attachdomain1()
has actually succeeded to initialize and attach. There is a theoretical
possibility to drop out early in if_attachdomain1() leaving the array
uninitialized if we cannot get the lock.

Split eventhandler_register() into an internal part and a wrapper function
that provides the allocated and setup eventhandler entry.
Add a new wrapper for VIMAGE that allocates extra space to hold the
callback function and argument in addition to an extra wrapper function.
While the wrapper function goes as normal callback function the
argument points to the extra space allocated holding the original func
and arg that the wrapper function can then call.
Provide an iterator function for the virtual network stack (vnet) that
will call the callback function for each network stack.
Provide a new set of macros for VNET that in the non-VIMAGE case will
just call eventhandler_register() while in the VIMAGE case it will use
vimage_eventhandler_register() passing in the extra iterator function
but will only register once rather than per-vnet.
We need a special macro in case we are interested in the tag returned
as we must check for curvnet and can neither simply assign the
return value, nor not change it in the non-vnet0 case without that.

never happens, but the leak is now plugged, just in case.
Harden the experimental NFS server a little, by adding extra checks
