Is that driver also possible for 6.2-RELEASE and 6-STABLE? This email is just for your information. Recently, I tried to port zyd(4) driver against RELENG_6 and the result, WIP version, come out here: http://weongyo.org/patches/zyd_RELENG_6-20071219.tar.gz However, this version does not work properly in RELENG_6. When you test this, you will succeed in attaching the device and getting IP address using dhclient(8) but you can see a lot of packet loss. I think that this problem come from the lack of MFCs of ieee80211 framework or USB framework to RELENG_6 because this version works well in CURRENT with small changes. After testing more cases, I will let you know when problems on RELENG_6 are solved.

config(8) patch for review for src dir handling
I've attached a patch I'd like to commit to config(8) for the way it
handles get_srcdir. I'm asking for review since it partially reverts
some changes made in revision 1.42 of usr.sbin/config/main.c and I'd
like to make sure there are no issues there.
Right now config(8) calls realpath(../.., ... to find the src path
to write into the kernel Makefile. I want to change this to use $PWD
with the last two path components removed, assuming it's the same dir
as ../.. .
I want to put this in because I often build from an amd(8)-mounted src
tree, and realpath produces a path using amd's special temporary mount
directory /.amd_mnt/... instead of the intended /host_mounts/... type of
path and it times out when accessed that way. Using the logical cwd
means that the generated Makefile references /host_mounts/... and amd
knows the mount is still in use when building.
Comments?

critical floating point incompatibility
Developers, There is a critical incompatibility between the floating point environment of the 32-bit compatibility environment of AMD64 systems and a genuine i386 system. The default setting of the x87 floating point control word on the i386 port is 0x127F. Among other things, this value sets the precision control to double precision. The default setting of the x87 floating point control word on the AMD64 is 0x37F. This value sets the precision control to double-extended precision. Since the AMD64 port uses SSE2 instructions for single and double precision arithmetic (thereby reserving the x87 for double-extended precision) this is a reasonable setting. Unfortunately, when a 32-bit binary is run under compatibility on an AMD64 system, the floating point control word is 0x37F, not 0x127F. 32-bit binaries do not expect the floating point environment to be in this state. The net effect is that all but the most trivial programs using x87 floating point arithmetic instructions will produce different values when run on a native i386 system than when run under compatibility on a 64-bit system! It seems clear that the right thing to do is to set the floating point environment to the i386 default for i386 binaries. Is the current behavior intended?

Some diffs
Consider the following diffs. The first one does a tiny cleanup of
strfile's include style (no real reason other than it bugged me when I
added stdint.h).
The second one cleans up a minor problem where ${CFLAGS} isn't used
where it should be.
The next three cleanup the compilation by not assuming sys/types.h is
included or by also including stdint.h
And the last, rather long, patch converts the .y in config to a form
that more versions of yacc would grok.
Comments?
