- The two types must be type-punnable for shared members of ifr_ifru.
This allows compatibility accessors to be shared.
- There must be no padding gap between ifr_name and ifr_ifru. This is
assumed in tcpdump's use of SIOCGIFFLAGS output which attempts to be
broadly portable. This is true for all current architectures, but very
large (256-bit) fat-pointers could violate this invariant.

The common pratice in ethernet device drivers is to fall back to
ether_ioctl() to implement generic ioctls not implemented by the driver
and to fail if no handler exists.
Convert these drivers to follow that practice rather than calling
ether_ioctl() for specific cases.
vxge(4) aready had the default case, but it was only called on failure
to match.

If the network interface or the uefi implementation do not support the
ReceiveFilter interface do not return only and just print a message.
U-Boot doesn't support is and likely never will. Also even if this fails
it doesn't mean that network in EFI isn't supported.
The ocs_fc(4) driver supports the following hardware:
Emulex 16/8G FC GEN 5 HBAS
LPe15004 FC Host Bus Adapters
LPe160XX FC Host Bus Adapters
Emulex 32/16G FC GEN 6 HBAS
LPe3100X FC Host Bus Adapters
LPe3200X FC Host Bus Adapters
The driver supports target and initiator mode, and also supports FC-Tape.
Note that the driver only currently works on little endian platforms. It
is only included in the module build for amd64 and i386, and in GENERIC
on amd64 only.

Strip @VER suffices from the LTO output.
This fixes pr36623.
The problem is that we have to parse versions out of names before LTO
so that LTO can use that information.
When we get the LTO produced .o files, we replace the previous symbols
with the LTO produced ones, but they still have @ in their names.
We could just trim the name directly, but calling parseSymbolVersion
to do it is simpler.
This is a follow-up to r331366, since we discovered that lld could
append version strings to symbols twice, when using Link Time
Optimization.

Mostly this is a thin shim around existing code to integrate with enc_xform
and cryptosoft (+ cryptodev).
Expand the cryptodev buffer used to match that of Chacha20's native block
size as a performance enhancement for chacha20_xform_crypt_multi.
Add a new "interleave" allocation policy which stripes pages across
domains with a stride or width keeping contiguity within a multi-page
region.
Move the kernel to the dedicated numbered cpuset #2 making it possible
to assign kernel threads and memory policy separately from user. This
also eliminates the need for the complicated interrupt binding code.
Add a sysctl API for viewing and manipulating domainsets. Refactor some
of the cpuset_t manipulation code using the generic bitset type so that
it can be used for both. This probably belongs in a dedicated subr file.

9188 increase size of dbuf cache to reduce indirect block decompression
illumos/illumos-gate@268bbb2a2f
With compressed ARC (6950) we use up to 25% of our CPU to decompress indirect
blocks, under a workload of random cached reads. To reduce this decompression
cost, we would like to increase the size of the dbuf cache so that more
indirect blocks can be stored uncompressed.
If we are caching entire large files of recordsize=8K, the indirect blocks
use 1/64th as much memory as the data blocks (assuming they have the same
compression ratio). We suggest making the dbuf cache be 1/32nd of all memory,
so that in this scenario we should be able to keep all the indirect blocks
decompressed in the dbuf cache. (We want it to be more than the 1/64th that
the indirect blocks would use because we need to cache other stuff in the
dbuf cache as well.)
In real world workloads, this won't help as dramatically as the example
above, but we think it's still worth it because the risk of decreasing
performance is low. The potential negative performance impact is that we
will be slightly reducing the size of the ARC (by ~3%).

In the case of zfs_compressed_arc_enabled=0, when the buf is returned via

is decremented by lsize, not psize.
Switch to using arc_buf_size(buf), instead of psize, which will return

9235 rename zpool_rewind_policy_t to zpool_load_policy_t
illumos/illumos-gate@5dafeea3eb
We want to be able to pass various settings during import/open of a pool,
which are not only related to rewind. Instead of adding a new policy and
duplicate a bunch of code, we should just rename rewind_policy to a more
generic term like load_policy.
For instance, we'd like to set spa->spa_import_flags from the nvlist,
rather from a flags parameter passed to spa_import as in some cases we want
those flags not only for the import case, but also for the open case. One
such flag could be ZFS_IMPORT_MISSING_LOG (as used in zdb) which would
allow zfs to open a pool when logs are missing.
