Libedit's vi mode provides a v command to edit the current line in vi(1)
(hard-coded to vi, in fact).
When Unicode/wide character mode was added, this command started truncating
and/or corrupting the edited text.
This commit fixes v if the text fits into the buffer. If the text is longer,
it is truncated.

Remove net.inet.tcp.experimental.initcwnd10 which is now redundant. Also remove
the parent node net.inet.tcp.experimental as it's not needed anymore and also
because it was not well thought out.

* refactor out the rx filter and operating mode code into a separate
method.
* add some comments about what's left with setting the operating mode
based on what carl9170 does.
* comment out some init from otus_init_mac() - it's no longer needed as
it's always init'ed now.
* add debugging and a missing return around a failure to call m_get2() -
during monitor mode operation I found RXing of frames > 2k, which
fails allocation. I'm sure they're valid (it's configuring 11n RX and
receiving 11n frames even though the driver doesn't "do" 11n)
and may be A-MSDU; but allocations fail and we should handle that
gracefully.
Tested:
* UB82 reference NIC (AR9170 + AR9104 2x2 dual band NIC); STA and
monitor mode operation.

code removes any overhead introduced by having IPSEC always in the

The IOAT hardware supports writing a 64-bit pattern to some destination
buffer. The same limitations on buffer length apply as for copy
operations. Throughput is a bit higher (probably because fill does not
have to spend bandwidth reading from a source in memory).
Support for testing Block Fill has been added to ioatcontrol(8) and the
ioat_test device. ioatcontrol(8) accepts the '-f' flag, which tests
Block Fill. (If the flag is omitted, the tool tests copy by default.)
The '-V' flag, in conjunction with '-f', verifies that buffers are
filled in the expected pattern.

CXXFLAGS to sub-makes.
The bad passing also causes bsd.dep.mk's logic to selectively pull only some
flags from C[XX]FLAGS to not apply which can be seen with '-L' being passed to
mkdep when using an external compiler.
Now on 24xx and above chips it is really possible to simulate several
virtual FC ports with single physical one. For example, it allows to
configure several targets in ctl.conf, assign each of them to separate
virtual port, and let user to control access to them with switch zoning.
I still doubt that all problems are solved there, but at now it passes
at least basic tests.
