Allow setting big MTU values on the pfsync interface but not larger
than the syncdev MTU. Prompted by the discussion with and tested
by Maxim Bourmistrov; ok dlg, mpf
Consistently use sc_ifp->if_mtu in the MTU check throughout the
module. This backs out r228813.
This was preventing the ath driver from being loaded at runtime.
It worked fine when compiled statically into the kernel but not when
kldload'ed after the system booted.
The root cause was that PCIR_INTLINE (register 60) was being
overwritten by zeros when register 62 was being written to.
A subsequent read of this register would return 0, and thus
the rest of the PCI glue assumed an IRQ resource had already
been allocated. This caused the device to fail to attach at
runtime as the device itself didn't contain any IRQ resources.
TODO: go back over the ar71xx and ar724x PCI config read/write
code and ensure it's correct.
value used in sys/ofed/include/linux/netdevice.h), so there will be no
buffer overruns in the rest of the inline functions in this file.

The wrong structure happened to work since the only argument used was
the vnode which is in the same place in both VOP_SETATTR() and the two
extattr VOPs.

I was thinking by myself, if the new code doesn't work with GCC 4.2, why
not simply turn it into an efficient version for C11 compilers? By
changing the code to use _Generic() directly in that case, I can build
the tgmath regression test in a matter of milliseconds with Clang,
instead of the 8 seconds it used to take.
So by the time C11 becomes the default, it will pick up the new code
automatically. And now I will refrain from making more changes to
<tgmath.h>.
Instead of using an exponential number of cases with respect to the
number of arguments, this version only uses a linear number.
Unfortunately, it works with Clang, GCC 4.6 and GCC 4.7, but not GCC
4.2. Therefore, leave it commented out.
consequence sbuf_len() will return -1 for buffers which had the error
status set prior to sbuf_finish() call. This causes a problem in
pfs_read() which purposely uses a fixed size sbuf to discard bytes which
are not needed to fulfill the read request.
Work around the problem by using the full buffer length when
sbuf_finish() indicates an overflow. An overflowed sbuf with fixed size
is always full.

This uses the existing crunchgen infrastructure to build
a series of tools designed to replace the base and networking
tools on an embedded system.
It reuses 'bsd.crunchgen.mk' to drive the actual file
creation. The rescue build system also uses this.
Unlike busybox, it doesn't include its own source - instead,
it just builds from the sources in /usr/src/ and leverages
the existing BSD framework.
Thie is still quite messy and could do with a whole lot of
cleaning up. However it is proving to be very useful with
my current build framework, allowing me to build binary root
images that are about 30% less than simply cherrypicking files
and libraries from an installworld.
so pid files can be written in /var/run when started as root.
I do not expect this to cause any security issues, but if anyone objects
it could be easily reverted.

than or equal to rcv_adv and fix tcp_twstart() to handle this case by
assuming the last window was zero rather than a negative value.
The code in tcp_input() already safely handled this case. It can happen
due to delayed ACKs along with a remote sender that sends data beyond
the window we previously advertised. If we have room in our socket buffer
for the extra data beyond the advertised window, we will accept it.
However, if the ACK for that segment is delayed, then we will not
effectively fixup rcv_adv to account for that extra data until the
next segment arrives and forces out an ACK. When that next segment
arrives, rcv_nxt will be beyond rcv_adv.
