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.

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.

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.

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.

To preserve the KPI, the previous operations are mapped to the write
lock macros. The lock is still kept as a mutex for now.

quite sure it's going about it the right way. More pondering is clearly
required.

Already introducing this allows us to be forward compatible with C11
compilers. By implementing <tgmath.h> on top of this interface, it
becomes trivial to support both our existing GCC and newer compilers.

For now, AH_SUPPORT_AR5416 is required, so I'll just fix any

only changed when the object is marked as OBJ_MIGHTBEDIRTY. For async
mode it is enough to write each dirty page, not to make a guarantee that
all pages are cleared after the vm_object_page_clean() returned.

after the IF_ADDR_LOCK is dropped. This removes a race where the lock
is dropped and reacquired while attempting to walk an interface's
