timestamps in the initial SYN packet actually use them in the rest of the
connection. Unfortunately, during the 7.0 testing cycle users have already
found network devices that violate this constraint.
RFC 1323 states 'and may send a TSopt in other segments' rather than
'and MUST send', so we must allow it.

publicly available datasheet for Yukon II and don't know what
bug/workaround exist for the specific hardware revision. Also I don't
think the vendor will release hardware errata in near future.
The hardware feature lists were not used at all except setting water
mark registers. Since msk(4) should know exact chip model/revision
number to decide which hardware capability could be used the extra
feature lists were redundant.
o Enable jumbo frame support for EC Ultra and disable jumbo frame
for FE.
o Enable store and forward mode for standard MTU sized frame.
o Enable TSO for EC Ultra. However TSO/checksum offload is disabled
for jumbo frame case. Because EC Ultra can't use store and forward
mode for jumbo frame TSO/checksum offload is not available.
o Adjust Tx GMAC almost empty threshold value and add a jumbo frame
water mark. The maic value was obtained from Marvell's sk98lin
driver.
o Fix EC Ultra chip revision number.

rwlocks in conjuction with callouts. The function does basically what
callout_init_mtx() alredy does with the difference of using a rwlock
as extra argument.
CALLOUT_SHAREDLOCK flag can be used, now, in order to acquire the lock only
in read mode when running the callout handler. It has no effects when used
in conjuction with mtx.
In order to implement this, underlying callout functions have been made
completely lock type-unaware, so accordingly with this, sysctl
debug.to_avg_mtxcalls is now changed in the generic
debug.to_avg_lockcalls.
Note: currently the allowed lock classes are mutexes and rwlocks because
callout handlers run in softclock swi, so they cannot sleep and they
cannot acquire sleepable locks like sx or lockmgr.

obstacle to enabling -Werror. I'll continue to work on cleaning up the
code so that we can keep this enabled.
If the tinderboxes would just use the default CFLAGS set in this file,
all would be fine and we'd be able to make use of -Werror.
Revert the probe in atapi-cd.c to the old usage now its fixed on AHCI.
THis change also fixes using virtual CD's om fx parallels.
Still leaves the GEOM problem of telling media vs device access apart in the access function.
server-side RPC retranmission cache for non-idempotent operations: these
hacks substituted 0 (success) for the expected EEXIST in the event that
a target name already existed for LINK, SYMLINK, and MKDIR operations,
under the assumption that EEXIST represented a second application of the
original RPC rather than a true failure.
Background: certain NFS operations (in this case, LINK, SYMLINK, and
MKDIR) are not idempotent, as they leave behind persisting state on the
server that prevents them from being replayed without an error;if an UDP
RPC reply is lost leading to a retransmission by theclient, the second
reply will return EEXIST rather than success, asthe new object has
already been created. The NFS client previouslysilently mapped the
EEXIST return into success to paper over thisproblem.
However, in all modern NFS server implementations, a reply cache is kept
in order to retransmit the original reply to a retransmitted request,
rather than performing the operation a second time, allowing this hack
to be avoided. This allows link()-based filelocking over NFS to operate
correctly, as an application requestingthe creation of a new link for a
file to tell if it succeededatomically or not.
Other NFS clients, including Solaris and Linux, generally follow this
behavior for the same reasons. Most clients also now default to TCP,
which also helps avoid the issue of retransmitted but non-idempotent
requests in most cases.

o buffered write, for chunks smaller than PIPE_MINDIRECT bytes
o direct write, for everything else
A call to writev(2) may receive struct iov of various size and the
kernel may have to switch from one solution to the other. Before doing
this, it must wake reader processes and any select/poll/kqueue up.
This commit fixes a bug where select/poll/kqueue are not triggered
when switching from buffered write to direct write. It adds calls to
pipeselwakeup().

This has the following benefits:
- allows to use the AT keyboard maps in share/syscons/keymaps with
sunkbd(4),
- allows to use kbdmux(4) with sunkbd(4),
- allows Sun RS232 keyboards to be configured and used the same
way as Sun USB keyboards driven by ukbd(4) (which also does AT
keyboard emulation) with X.Org, putting an end to the problem
of native support for the former in X.Org being broken over and
over again.

Currenty, lockmgrs and rmlocks don't have assertions, so just panic in
that case.
This will be a base for more callout improvements.

strees2 suite, to quote his letter, this change:
1. It removes the tn_lookup_dirent stuff. I think this cannot be fixed,
because nothing protects vnode/tmpfs node between lookup is done, and
actual operation is performed, in the case the vnode lock is dropped.
At least, this is the case with the from vnode for rename.
For now, we do the linear lookup in the parent node. This has its own
drawbacks. Not mentioning speed (that could be fixed by using hash), the
real problem is the situation where several hardlinks exist in the dvp.
But, I think this is fixable.
2. The patch restores the VV_ROOT flag on the root vnode after it became
reclaimed and allocated again. This fixes MPASS assertion at the start
of the tmpfs_lookup() reported by many.
