constructing a struct aio and invoking VOP_READ() directly. This cleans
up the code a little, but also has the advantage of making sure almost
all vnode read/write access in the kernel goes through the helper
function, meaning that instrumentation of that helper function can impact
almost all relevant read/write operations. In this case, it permits us
to put MAC hooks into vn_rdwr() and not modify uipc_syscalls.c (yet).
In general, if helper vn_*() functions exist, they should be used in
preference to direct VOP's in system call service code.

needed in the current code, in the MAC tree, create_init() relies on the
ability to modify the credentials present for initproc, and should not
perform that modification on a shared credential. Pro-active diff
reduction against MAC changes that are in the queue; also facilitates
other work, including the capabilities implementation.

(Currently lack of their specification does not lead to any problem, because
kernel does not check the consistency between actual address and its
address family / length on raw socket.
However kernel should always check their consistency and stop sending packets
if there is a contradiction. Considering backward compatibility of
programs, I just fixed rtsol now; I'd like to fix the kernel behavior later.)

Notice that if the device on which the dump is set is destroyed for
any reason, the dump setting is lost. This in particular will
happen in the case of spoilage. For instance if you set dump on
ad0s1b and open ad0 for writing, ad0s* will be spoilt and the dump
setting lost. See geom(4) for more about spoiling.

of this code. I very much doubt that "the FreeBSD way" really means "make
it as unreadable and unmaintable as possible", and I would like Makefile
style (which is not currently documented anywhere except in the minds of
bde and ru) to be discussed and agreed upon in the appropriate forum
before any further commits of this kind happen.

This is untested, but the code would rot even further if this wasn't
applied. I've chosen to apply this to prompt some cleanup.

Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick()
routine. dc_tick() is called regularly to detect link up and link down
status, especially when autonegotiating.
The expectation was that mii_tick() (which is still called from dc_tick())
would update status information automatically in all cases where it would
be sensible to do so.
Unfortunately, with authentic 21143 chips this is not the case, and
the driver never successfully autonegotiates. This is because (despite
what it says in the 21143 manual) the chip always claims that link is not
present while the autonegotiation enable bit is set. Autonegotation takes
place and succeeds, but the driver tests the link bits before it switches
off the autonegotiation enable bit, and success is not recognised.
The simplest solution is to call dcphy_status() more often for MII_TICK
calls by dropping out of the switch statement instead of exiting when
we are autonegotiating and link appears to not be present. When
autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx
state and turn off the autonegotiation enable bit. The next call to
dcphy_status() will notice that link is present, and the dc driver code
will be notified.
Macronix chips also use this code, but implement link detection as
described in the manual, and hence don't need this patch. However, tests
on a Macronix 98715AEC-C show that it does not adversely affect them.
This could be done better but is the minimal effective change, and most
closely mimics what was happening prior to rev 1.56 of if_dc.c. (Actually
I also deleted a small amount of unnecessary code while I was in the area.)
