* Split whiny skip function to create a new best-effort skip_lenient()
* Correctly increment the top-level file position only for the top filter
* Simulate skip by reading against the current filter, not the top filter
The latter two bugs aren't currently visible because no existing
filter delegates skip operations.
used for s/w retransmit schemes that want to access this information
w/o the overhead of decoding the raw frame. Note this also allows
drivers to record this information w/o writing the frame when the seq#
is obtained through an out-of-band mechanism (e.g. when a h/w assigned
seq# is reported in a descriptor on tx done notification).

This saves us from unnecessary IPFW_RLOCK(), m_tag_find() calls and
ip/tcp/udp header parsing.

controllers may be configured as legacy IDE mode by modifying subclass and
progif without actually changing PCI device IDs. Instead of complicating
code, we always force AHCI mode while probing. Also we restore AHCI mode
while resuming per ATI/AMD register programming/requirement guides.
- Fix SB700/800 "combined" mode. Unlike SB600, this PATA controller can
combine two SATA ports and emulate one PATA channel as primary or secondary
depending on BIOS configuration. When the combined mode is disabled, this
channel disappears and it works just like SB600 PATA controller, however.
- Add more PCI device IDs for SB700/800 and adjust device descriptions.
SB800 shares the same PCI device IDs and added two more SATA IDs.
the nfsv4 Change attribute. There are 2 changes:
1 - The value now changes on metadata changes as well as data
modifications (incremented for IN_CHANGE instead of IN_UPDATE).
2 - It is now saved in spare space in the on-disk i-node so that it
survives a crash.
Since va_filerev is not passed out into user space, the only current
use of va_filerev is in the nfs server, which uses it as the directory
cookie verifier. Since this verifier is only passed back to the server
by a client verbatim and then the server doesn't check it, changing the
semantics should not break anything currently in FreeBSD.

this driver to compile and limp along with the new layer. These changes
do not deal with proper locking around access to the HW. This is only
a starting point. I have not tested modem control but tip seems to work
okay and I can send and receive characters which I needed for one of my
-current boxes. I have not tied this driver back up to the build since
I don't want people to think it is ready for prime time. If anyone
else has some cycles to work on this feel free to!
Also add support for a 16 port PCI interface I have at work.

- Update mxge to use if_transmit(), and the new buf_ring
interfaces, so as to enable multiple transmit queues.
Use of if_transmit() is conditional on IFNET_BUF_RING,
and is enabled by default (as in if_em).
- Record a flow id on receive if receive hashing is active.
I currently only record the rx ring id (0..8) rather than
the 32-bit topelitz hash result, as doing the latter would
require shifting the driver to use a larger rx return ring.

Instead of using the antique insque()/remque() functions from
sys/queue.h, make this code use its own versions. Eventually the code
should just use the regular TAILQ/LIST macros.
(colloquially known as if_addrlist). Currently not acquired around
interface address loops that call out to the routing code due to
potential lock order issues.

access to the file data (if the file exists on
disk). This was broken for the first regular
file; fix it and add a test so it won't break again.
In particular, this fixes the following idiom for creating
a tar archive in which every file is owned by root:

While here, introduce a crude hack aimed at preventing ng_ether to
