As sc(4) and vt(4) coexist and are both enabled in GENERIC, the existence
of a vt(4) sysctl is not sufficient to determine that vt(4) is in use.
Reported by: Trond Endrestøl
Both vt(4) and ofwfb(4) need a lot of love to be usable on sparc64 and even
then the performance of ofwfb(4) would suck compared to hardware accelerated
drivers like creator(4) and machfb(4).
The UEFI framebuffer driver vt_efifb requires vt(4), so add a mechanism
for the startup routine to set the preferred console. This change is
ugly because console init happens very early in the boot, making a
cleaner interface difficult. This change is intended only to facilitate
the sc(4) / vt(4) transition, and can be reverted once vt(4) is the
default.
1. oce_multiq_start(): make sure the buffer is consumed even on ENXIO
2. oce_multiq_transmit(): there is an extra call to drbr_enqueue()
causing the mbuf to be enqueued twice when the NIC's queue is full,
and potential panics
3. oce_multiq_transmit(): same problem fixed recently in ixgbe (r267187)
and other drivers: if the mbuf is enqueued, the proper return value is 0

on the semantics of non-NFSv4.1 server behaviour.
It is a rather large merge, but I am hoping that there will
not be any regressions for the NFS server.

UFS rather than for all but ZFS. This code was assuming that offsets were
monotonically increasing for all file systems except ZFS and that the
cookies from a previous call may have been rewound to a block boundary.
According to mckusick@ only UFS is known to do this, so only requests against
UFS file systems should remove cookies smaller than the given offset. This
fixes serving TMPFS over NFS as it too does not have monotonically increasing
offsets. The comment around the code also indicated it was specific to UFS.
Some of the code using 'not_zfs' is specific to ZFS snapshot handling, so
add a 'is_zfs' variable for those cases.
It's possible that 'is_zfs' check for VFS_VGET() support may not be
specific to ZFS. This needs more research and testing.
After this fix TMPFS and other file systems can be served over NFS.
To test I compared the results of syncing a /usr/src tree into a tmpfs and
serving that over NFS. Before the fix 3589 files were missing on the remote
view. After the fix all files were successfully found.

r262491:
Add DEBUG_DISTRIBUTIONS, and set it to include base and
EXTRA_DISTRIBUTIONS, excluding 'doc', since the documentation
distribution does not have corresponding debug information.
Use DEBUG_DISTRIBUTIONS in the 'distributeworld installworld'
and 'packageworld' targets, to reduce the number of occurances
of excluding distributions that do not have .debug files.
r262493:
In release/Makefile, explicitly set WITHOUT_DEBUG_FILES=1
for dvdrom and cdrom targets. (Later reverted.)
Exclude the *.debug.txz distributions from dvdrom and
cdrom images, but include them for ftp distribution.
r262516:
Rename ${dist}.debug.txz to ${dist}-dbg.txz to prevent the
following output:
eval: ${base....}: Bad substitution
eval: ${doc....}: Bad substitution
eval: ${games....}: Bad substitution
eval: ${lib32....}: Bad substitution
This also follows other naming conventions seen in the
wild.
r267345:
Explicitly set MK_DEBUG_FILES=no, which overrides the
WITH_DEBUG_FILES=1 and WITHOUT_DEBUG_FILES=1 collisions
previously experienced.
This change allows us to create the {base,kernel}_debug.txz
distributions without accidentally installing the *.debug
files on the medium itself.
r267397:
Remove evaluations of MK_DEBUG_FILES where not needed.
If DEBUG_DISTRIBUTIONS is empty, which is true if
MK_DEBUG_FILES evaluates to 'no' above, the loop does
nothing.

For every supported command define CDB length and mask of bits that are
allowed to be set. This allows to remove bunch of checks through the code
and still make the validation more strict. To properly do it for commands
supporting multiple service actions, formalize their parsing by adding
subtables for each of such commands.
As visible effect, this change allows to add support for REPORT SUPPORTED
OPERATION CODES command, reporting to client all the data about supported
SCSI commands, except timeouts.
