o adding locking to op submission
o mark interrupt handler MPSAFE
o don't use locking on detach; disabling interrupts should be sufficient
o change mutex string names so witness printouts are more meaningful
Note: locking is still pretty brute-force but it's probably not worth
improving it given the relatively low performance of hifn-based cards.
o replace driver-global lock with three locks: one for the handling of mcr1
operations, one for handling of mcr2 operations, and one for the mcr1
free list
o mark the interrupt handler MPSAFE
o don't use locking on detach; disabling interrupts is sufficient (I think)
o add a ``done'' flag for crypto operations; this is set when the operation
completes and is intended for callers to check operations that may complete
``prematurely'' because of direct callbacks
o close a race for operations where the crypto driver returns ERESTART: we
need to hold the q lock to insure the blocked state for the driver and any
driver-private state is consistent; otherwise drivers may take an interrupt
and notify the crypto subsystem that it can unblock the driver but operations
will be left queued and never be processed
o close a race in /dev/crypto where operations can complete before the caller
can sleep waiting for the callback: use a per-session mutex and the new done
flag to handle this
o correct crypto_dispatch's handling of operations where the driver returns
ERESTART: the return value must be zero and not ERESTART, otherwise the
caller may free the crypto request despite it being queued for later handling
(this typically results in a later panic)
o change crypto mutex ``names'' so witness printouts and the like are more
meaningful
all the argument registers etc since we have almost certainly have trashed
them by now. Take particular car of %r10 since it held the original value
of %rcx (which we saved in tf_rcx on entry and doreti doesn't know this).
Change the list interface to simplify things.
Remove old list ioctls which bogusly exported the softc to userland.
Move the softc and associated structures from the public header to
the source file.
Make CCD a GEOM class.
For now only use this for implementing a OAM config method which
can return a list of configured CCD devices in the format which
"ccdconfig -g[v]" would normally output.
mpo_copy_mbuf_label() entry point for Biba and MLS, respectively.
Otherwise, labels in m_tags may not be properly propagated across
some classes of mbuf operations. This problem caused these policies
to fail-stop the system with a panic.

Two tokens that don't together form a vaid preprocssor token cannot be
pasted together using ANSI-C token concatinatation. GCC 3.2's cpp, at least,
produces the desired result w/o using "##".
Clarify that the implicit fallthrough was *not* intentional (thanks, Poul!)
and reorganize the code so a correct fallthrough (with /* FALLTHROUGH */)
occurs.
o Use pcb and tf for the new pcb and the new trapframe and use pcb0
for the old (current) pcb. The mix of pcb, pcb2 and tf was slightly
confusing.
o Don't define td->td_frame here. It has already been set previously
by cpu_thread_setup. Add a KASSERT to make sure pcb and tf are both
non-NULL.
o Make sure the number of dirty registers is 0 for the new thread.
There are no user registers on the backing store because we heven't
enter userland yet.
is not called, and no static rules match an outgoing packet, the
latter retains its source IP address. This is in support of the
"static NAT only" mode.
bzero(ptr, sizeof(DC_RXLEN * 5));
which should obviously be:
bzero(ptr, DC_RXLEN * 5);
Looks like this bug may have reduced the effectiveness of the
workaround for the hardware bug in the PNIC chips.
MFC after: 1 week
o Remove register keyword
o ANSIfy prototypes
o Remove "return;" at the end of void functions
o Remove trailing spaces
o Don't align local variables with tabs and reorder them
o Don't use /* FOO */ at the end of a #ifdef FOO block if
it's a small block
- Other non-functional changes :
o 6 -> ETHER_ADDR_LEN
o Don't initialize if_output; ether_ifattach() does it for us
