According to config(5), the "device", "devices",
"nodevice", "nodevices", "option", "options",
"nooption", and "nooptions" keywords can all take a
comma-separated list of values. However, the yacc code
did not allow lists for "nooption" and "nooptions", only
single values. This commit fixes the yacc code to allow
comma separated values for all the above keywords.

I edited the original change to retain the use of arc4random() as a seed for
the hashing as a very basic defense against intentional lagg port selection.
The author's original commit message (edited slightly):
sys/net/ieee8023ad_lacp.c
sys/net/if_lagg.c
In lagg_hashmbuf, use the FNV hash instead of the old
hash32_buf. The hash32 family of functions operate one octet
at a time, and when run on a string s of length n, their output
is equivalent to :
----- i=n-1
\
n \ (n-i-1) 32
( seed^ + / 33^ * s[i] ) % 2^
/
----- i=0
The problem is that the last five bytes of input don't get
multiplied by sufficiently many powers of 33 to rollover 2^32.
That means that changing the last few bytes (but obviously not
the very last) of input will always change the value of the
hash by a multiple of 33. In the case of lagg_hashmbuf() with
ipv4 input, the last four bytes are the TCP or UDP port
numbers. Since the output of lagg_hashmbuf is always taken
modulo the port count, and 3 is a common port count for a lagg,
that's bad. It means that the UDP or TCP source port will
never affect which lagg member is selected on a 3-port lagg.
At 10Gbps, I was not able to measure any difference in CPU
consumption between the old and new hash.

add two targets, 'vm-release' and 'cloudware-release',
that are invoked if WITH_VMIMAGES and WITH_CLOUDWARE

This fixes an issue where 'make release' would not
build the cloud provider targets because CLOUDWARE was
not yet set. [1]
Move the WITH_VMIMAGES and WITH_CLOUDWARE targets to
Makefile.vm.
Note: There is no 'cloudware-install' target yet, since
some of the disk image names may need to be specific to
the provider, so this is probably best handled by the
build scripts.

very questionable, since it makes vimages more dependent on each other. But
the reason for the backout is that it screwed up shutting down the pf purge
threads, and now kernel immedially panics on pf module unload. Although module
unloading isn't an advertised feature of pf, it is very important for
development process.
I'd like to not backout r276746, since in general it is good. But since it
has introduced numerous build breakages, that later were addressed in
r276841, r276756, r276747, I need to back it out as well. Better replay it
in clean fashion from scratch.
While here, fix a bug in which NANO_PMAKE would not be appended at the
appropriate time.
Simply move both checks to after the call to set_defaults_and_export().

The newer boards don't have the response field that indicates
whether the SCSI status byte is present. You have to just look to
see whether it is non-zero.
The code was looking to see whether the sense length was valid
before propagating the SCSI status byte (and sense information) up
the stack. With a status like Reservation Conflict, there is no
sense information, only the SCSI status byte. So it wasn't getting
correctly returned.
isp.c:
In isp_intr(), if we are on a 2400 or 2500 type board and
get a response, look at the actual contents of the
SCSI status value and set the RQSF_GOT_STATUS flag
accordingly so that return any SCSI status value we get. The
