aa959e0d17 Update support for 795x parts:
o rework pll setup code to follow h/w specification
o add hint.hifn.X.pllconfig to specify reference clock setup
  requirements; default is pci66 which means the clock is
  derived from the PCI bus clock and the card resides in a
  66MHz slot

Tested on 7955 and 7956 cards; support for 7954 cards not enabled
since we have no cards to test against.

In collaboration with Poul-Henning Kamp.

fe9b390b9d Move session state from on-card memory to host memory so we no longer are
constrained to a small number of sessions by the small on-card memories found
in newer devices.  This is really a stopgap solution as having session state
in main memory incurs a (small but noticeable) performance penalty. The better
solution is to manage session state so that it's cached on chip.

5c5c7982be Use the external clock input for our PLL.
This may not be a generally valid configuration, but neither is relying
on the PCI clock to be stable.

The only currently known and supported hardware is the VPN14x1 from
Soekris, and since it has external clock, we fail safe(r) by using
it.

Unfortunately there is no way to probe this reliably.

c06eb4e293 Change instances of callout_init that specify MPSAFE behaviour to

does not change the behaviour; it just makes the intent more clear.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

07d0c94a46 Add support to eliminate a context switch per crypto op when using the
software crypto device:

o record crypto device capabilities in each session id
o add a capability that indicates if the crypto driver operates synchronously
o tag the software crypto driver as operating synchronously

This commit also introduces crypto session id macros that cleanup their
construction and querying.

4f28f7d769 Redo locking for better SMP suport:
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.

9967cafc49 Correct mbuf packet header propagation. Previously, packet headers
were sometimes propagated using M_COPY_PKTHDR which actually did
something between a "move" and a  "copy" operation.  This is replaced
by M_MOVE_PKTHDR (which copies the pkthdr contents and "removes" it
from the source mbuf) and m_dup_pkthdr which copies the packet
header contents including any m_tag chain.  This corrects numerous
problems whereby mbuf tags could be lost during packet manipulations.

These changes also introduce arguments to m_tag_copy and m_tag_copy_chain
to specify if the tag copy work should potentially block.  This
introduces an incompatibility with openbsd which we may want to revisit.

Note that move/dup of packet headers does not handle target mbufs
that have a cluster bound to them.  We may want to support this;
for now we watch for it with an assert.

Finally, M_COPYFLAGS was updated to include M_FIRSTFRAG|M_LASTFRAG.
