3 Fixes -
a) There was a case where a ICMP message could cause
us to return leaving a stuck lock on an stcb.
b) The iterator needed some tweaks to fix its lock
ordering.
c) The ITERATOR_LOCK is no longer needed in the freeing
of a stcb. Now that the timer based one is gone we don't
have a multiple resume situation. Add to that that there
was somewhere a path out of the freeing of an assoc that
did NOT release the iterator_lock.. it was time to clean
this old code up and in the process fix the lock bug.

A number of netfront fixes and stability improvements:
- Re-enable TSO. This was broken previously due to CSUM_TSO clearing the
CSUM_TCP flag, so our checksum flags were incorrectly set going to the
netback driver. That was fixed in r206844 in tcp_output.c, so we can
turn TSO back on here.
- Fix the way transmit slots are calculated, so that we can't overfill
the ring.
- Avoid sending packets with more fragments/segments than netback can
handle. The Linux netback code can only handle packets of
MAX_SKB_FRAGS, which turns out to be 18 on machines with 4K pages. We
can easily generate packets with 32 or so fragments with TSO turned on.
Right now the solution is just to drop the packets (since netback
doesn't seem to handle it gracefully), but we should come up with a way
to allow a driver to tell the TCP stack the maximum number of fragments
it can handle in a single packet.
- Fix the way the consumer is tracked in the receive path. It could get
out of sync fairly easily.
- Use standard Xen ring macros to make it clearer how netfront is using
the rings.
- Get rid of Linux-ish negative errno return values.
- Added more documentation to the driver.
- Refactored code to make it easier to read.
- Some other minor fixes.

Program the K2 SATA controller's interrupt to be level-triggered low, and
respect the edge/level settings in the device tree.
OpenPIC on powerpc sets interrupts to be level high by default. On Apple
interrupt controllers, all level interrupts are low regardless of
programming except interrupt 0, used by K2 SATA on some Apple systems, with
the result that the K2 SATA IRQ is misconfigured. Pending review of changes
to this default, work around this by changing the programming of the K2
SATA interrupt to level low.

Some revisions of the Serverworks K2 SATA controller have a data
corruption bug where if an ATA command is issued before DMA is started,
data will become available to the controller before it knows what to do
with it. This results in either data corruption or a controller crash.
This patch remedies the problem by adopting the workaround employed
by Linux and Darwin: starting the DMA engine prior to sending the ATA
command.

More gracefully handle stale file handles and attributes when opening a
file via NFS. Specifically, to satisfy close-to-open-consistency, the NFS
client always performs at least one RPC on a file during an open(2) to see
if the file has changed. Normally this RPC is an ACCESS or GETATTR RPC
that is forced by flushing a file's attribute cache during nfs_open() and
then requesting new attributes. However, if the file is noticed to be
stale during nfs_open(), the only recourse is to fail the open(2) call
with ESTALE. On the other hand, if the ACCESS or GETATTR RPC is sent
during nfs_lookup(), then the NFS client can fall back to a LOOKUP RPC to
obtain the new file handle in the case that a file has been replaced.
This change causes the NFS client to flush the attribute cache during
nfs_lookup() when validating a name cache hit if the attributes fetched
during nfs_lookup() can be reused in nfs_open(). This allows the client
to open a replaced file via the new file handle the first time that it
notices a replaced file rather than failing with ESTALE in some cases.

Fix a bug introduced in r199011. When bge(4) reuses loaded RX
buffers it should also reinitialize RX descriptors otherwise some
stale data could be passed to controller. This could end up with
mbuf double free or unexpected NULL pointer dereference in upper
stack. To fix the issue, save loaded buffer's length and
reinitialize RX descriptors with the saved value whenever bge(4)
reuses the loaded RX buffers.
While I'm here, increase the number of RX buffers to 512 from 256.
This simplifies RX buffer handling as well as giving more RX
buffers. Controller supports just fixed number of RX buffers
(i.e. 512) and bge(4) used to rely on hope that our CPU is fast
enough to keep up with the controller. With this change, bge(4)
will use 1MB for RX buffers but I don't think it would cause
problems in these days.
