frame processing according to amendment as following:
o Fixed PREP to always update/create if acceptance criteria is meet;
o PREQ processing to reply if request is for a proxy entry that is
proxied by us;
o Removed hwmp_discover call from PREQ, because sending a PREP will
build the forward path, and by receving and accepting a PREQ we
have already built the reverse path (non-proactive code);

pro-active HWMP routing later)

arge1 still works (it's the standalone PHY) but arge0 and the other switch
ports don't work. They're enumerated though, demonstrating that the
mdiobus abstraction is correctly working.
This is only done if the ARGE_MDIO option is included.
* Shuffle the arge MDIO bus into a separate device, that needs to be
probed early (use hint.argemdio.X.order=0)
* hint.arge.X.mdio now specifies which miiproxy to rendezvous with.
* Call MAC/MDIO bus init during MDIO attach, not arge attach.
This is done regardless:
* Shift the arge MAC and MDIO bus reset code into separate functions
and call it early during MDIO bus attach. It's required for
correct MDIO bus IO to occur on AR71xx/AR91xx devices.
* Remove the AR71xx/AR91xx centric assumption that there's only one
MDIO bus. The initial code mapped miibus0(arge0) and miibus1(arge1)
MII register operations to the MII0 (arge0) register space. The
AR724x (and later, upcoming chipsets) have two MDIO busses and
the second is very much in use.
TODO:
* since the multiphy behaviour has changed (where now a phymask of >1
PHY will still be enumerated), multiphy setups may be quite wrong.
I'll go and fix these so they still have a chance of working, at least.
until the switch PHY support appears in -HEAD.

MDIO/MII rendezvous proxy.
* Add an 'mdio' bus, which is the "IO" side of an MII bus (but by design
can be anything which implements the underlying register access API.)
* Add 'miiproxy' and 'mdioproxy', which provides a rendezvous mechanism
for MII busses to appear hanging off arbitrary busses (ie, that aren't
necessarily a traditional looking MII bus.)
MII busses can now hang off anything that implements an mdiobus.
For the AR71xx SoC, there's one MDIO bus but two MII busses. So to
properly support two or more real PHYs, this can be done:
# arge0 MDIO bus - there's no arge1 MDIO bus for AR71xx
hint.argemdio.0.at="nexus0"
hint.argemdio.0.maddr=0x19000000
hint.argemdio.0.msize=0x1000
hint.argemdio.0.order=0
# Create two mdioproxy instances
hint.mdioproxy.0.at="mdio0"
hint.mdioproxy.1.at="mdio0"
# .. and with a follow-up patch
hint.arge.0.mdio=mdioproxy0
hint.arge.1.mdio=mdioproxy0
TODO:
* Do a sweep or two and add appropriate locking in mdio/mdioproxy/miiproxy.

Simply by moving the #include_next off the header protection, we allow

Supports multiple volumes per array and multiple partitions per disk.
Supports standard big-endian and Adaptec's little-endian byte ordering.
Supports all single-layer RAID levels. Dual-layer RAID levels except
RAID10 are not supported now because of GEOM RAID design limitations.
Some work is still to be done, but the present code already manages basic

1. Rewrite the way growfs(8) finds the device and mount point. This makes
it possible to use e.g. "growfs /mnt"; it's also used to display more
helpful messages.
2. Be more user-friendly, using descriptive messages, like this:
OK to grow filesystem on /dev/md0, mounted on /mnt, from 9.8GB to 20GB? [Yes/No]"
3. Allow to specify the size (-s option) just like with mdconfig(8), i.e. with
postfixes ("mdconfig -s 10g").
4. Reload read-only filesystem after growing.

The typical case was:
static __inline int
convert_ccl(FILE *fp, char * __restrict p, [...])
{
[...]
if (p == SUPPRESS_PTR) {
[...]
} else {
[...]
}
[...]
}
This qualifier says that the pointer is the only one at that time
pointing to the resource.
Here, clang considers that "p" will never match "SUPPRESS_PTR" and
optimize the if{} block out. This leads to segfaults in programs calling
vfscanf(3) and vfwscanf(3) with just the format string (no arguments
following it).
The following softwares were reported to abort with segmentation fault
and this patch fixes it:
o cmake
o smartd
o devel/ORBit2
