MFC r344316 (by pjd):
The way ZFS searches for its vdevs is the following: first it looks for
a vdev that has the same name as the one stored in metadata and that has
all VDEV labels in place. If it cannot find a GEOM provider with the given
name and all VDEV labels it will scan all GEOM providers for the best match
(the most VDEV labels available), but here the name is ignored.
In case the ZFS pool is created, eg. using GPT partition label:
# zpool create tank /dev/gpt/tank
everything works, and on every import ZFS will pick /dev/gpt/tank and
not /dev/da0p4.
The problem occurs when da0p4 is extended and ZFS is unable to find all
VDEV labels in /dev/gpt/tank anymore (the VDEV labels stored at the end
of the partition are now somewhere else). In this case it will scan all
GEOM providers and will pick the first one with the best match, ie. da0p4.
Fix this problem by checking the VDEV/provider name even if we get the same
match. If the name is the same as the one we have in pool's metadata, prefer
this GEOM provider.

As I see, different NICs in different configurations may have different

is set to maximum of TX and RX queues, when those two are different, the

The `zfs userspace` squashes all entries with unresolved numeric

made by the string name which is empty in case of unresolved IDs.
Fix this by falling to a numerical comparison when either one
of string values is not found. This then compares any numerical
values after all with a name resolved.

MFC r348059: vt efifb: add suspend/resume calls
Using the latest NVIDIA driver, upon resuming from suspend with X
running the display remained blank. Additionally OpenGL applications
that were running triggered a number of error messages from the NVIDIA

This occurred because the vt efifb back-end did not signal the X server
to release the display before suspending (or to re-acquire it after
resuming). The NVIDIA driver includes code for smoothly shutting down
and re-initializing the GPU, which was not getting called.
Since the NVIDIA driver doesn't currently support framebuffer devices
and vt is forced to fall back to the efifb back-end, add vd_suspend and
vd_resume members to connect the suspend/resume path. This ensures the
X server is properly able to re-initialize the display.
