When sending export datagram from interrupt thread, use NG_QUEUE
in flags. When sending export datagram from expiry thread, then
use default zero flags. This removes unpleasant contention of the
interrupt thread on mutexes (usually ng_ksocket's socket buffer
mutex).
Do not force queueing on peer hooks. This was important only for
5.0-CURRENT. And it looks like this didn't work before Julian's
revamp of netgraph queue code.

Mark appropriate commands with NGM_READONLY and NGM_HASREPLY and
bump type cookie.
This fixes flowctl(8) exiting without any output under high load on SMP.
Provide additional macros for sending netgraph items, which allow
to use non-default flags for netgraph functions. Implement current
macros via new ones.
Add support for the Wacom Graphire 3 4x5. Like the Graphire 3, it has a
broken report descriptor. While I'm here, make all the other report
descriptors const to match the newly added one.
Add support for Xbox 360 gamepads. They are HID-capable devices, but
lack a report descriptor and don't use the standard interface class.
This patch works around these deficiencies so that the uhid(4) driver
can recognize and use those broken devices.

- Workaround for sb16 behave poorly when running at 45000 hz while
vchan is enabled.
Ruthless vchan speed workaround against the dreaded sb16 / sb16x.
It appear that nothing else using this weird 45k / 49k speed upper
limit.
- Raise VCHAN_DEFAULT_SPEED from 44100 to 48000.
Reported by: many sb16, AWE64 users.
markable changes are:
o Suspend/resume methods.
o Link state detection fixes.
o Utilization of jumbo allocator and extended RX descriptors.
o busdma(9) cleanup and support for big-endian architectures.
o Improved checksum offloading support.
o Reduced number of PCI register writes in bge_start().
o Counting RX/TX errors as input/output interface errors.
struct mbuf *m_getjcl(int how, short type, int flags, int size)
void *m_cljget(struct mbuf *m, int how, int size)
For size both take MCLBYTES, MJUM4BYTES, MJUM9BYTES, MJUM16BYTES.

In realloc(9), determine size of the original block based on
UMA_SLAB_MALLOC flag.
In some circumstances (I observed it when I was doing a lot of reallocs)
UMA_SLAB_MALLOC can be set even if us_keg != NULL.
If this is the case we have wonderful, silent data corruption, because less
data is copied to the newly allocated region than should be.
Add a new feature for optimizining ipfw rulesets - substitution of the
action argument with the value obtained from table lookup. The feature
is now applicable only to "pipe", "queue", "divert", "tee", "netgraph"
and "ngtee" rules.
Optimize parallel processing of ipfw(4) rulesets eliminating the locking
of the radix lookup tables. Since several rnh_lookup() can run in
parallel on the same table, we can piggyback on the shared locking
provided by ipfw(4).
However, the single entry cache in the ip_fw_table can't be used lockless,
so it is removed. This pessimizes two cases: processing of bursts of similar
packets and matching one packet against the same table several times during
one ipfw_chk() lookup. To optimize the processing of similar packet bursts
administrator should use stateful firewall. To optimize the second problem
a solution will be provided soon.
Details:
o Since we piggyback on the ipfw(4) locking, and the latter is per-chain,
the tables are moved from the global declaration to the
struct ip_fw_chain.
o The struct ip_fw_table is shrunk to one entry and thus vanished.
o All table manipulating functions are extended to accept the struct
ip_fw_chain * argument.
o All table modifing functions use IPFW_WLOCK_ASSERT().
First step in removing welding between ipfw(4) and dummynet.
o Do not use ipfw_insn_pipe->pipe_ptr in locate_flowset(). The
_ipfw_insn_pipe isn't touched by this commit to preserve ABI
compatibility.
o To optimize the lookup of the pipe/flowset in locate_flowset()
introduce hashes for pipes and queues:
- To preserve ABI compatibility utilize the place of global list
pointer for SLIST_ENTRY.
- Introduce locate_flowset(queue nr) and locate_pipe(pipe nr).
o Rework all the dummynet code to deal with the hashes, not global
lists. Also did some style(9) changes in the code blocks that were
touched by this sweep:
- Be conservative about flowset and pipe variable names on stack,
use "fs" and "pipe" everywhere.
- Cleanup whitespaces.
- Sort variables.
- Give variables more meaningful names.
- Uppercase and dots in comments.
- ENOMEM when malloc(9) failed.
