a pointer to an ifaddr matching the passed socket address, returns a
boolean indicating whether one was present. In the (near) future,
ifa_ifwithaddr() will return a referenced ifaddr rather than a raw
ifaddr pointer, and the new wrapper will allow callers that care only
about the boolean condition to avoid having to free that reference.

Note that I also added the usbdev to the list, because the 8813 version
is not yet known there. I might have twisted the sorting there but because
8813 comes before 8818, I added it before that (with _8813 to differentiate)
the item.

To detect which controller is ICH based one, add a new member
variable ich to struct fxp_ident and move the struct to
if_fxpvar.h. Since I've faked controller revision, don't allow
microcode loading for ICH based controllers.
With this change all ICH based controllers will have WOL and Rx
checksum offload capability.

not allow multicast filter programming when controller is busy to
send/receive frames. So it used to mark need_mcsetup bit and defer
multicast filter programming until controller becomes idle state.
To detect when the controller is idle fxp(4) relied on Tx
completion interrupt with NOP command and fxp_start_body and
fxp_intr_body had to see whether pending multicast filter
programming was requested. This resulted in very complex logic and
sometimes it did not work as expected.
Since the controller should be in idle state before any multicast
filter modifications I changed it to reinitialize the controller
whenever multicast filter programming is required. This is the same
way what OpenBSD and NetBSD does. Also I added IFF_DRV_RUNNING
check in ioctl handler so controller would be reinitialized only if
it is absolutely needed.
With this change I guess we can remove fxp(4) DELAY hack in ifioctl
for IPv6 case.
upper stack in fxp_start_body().
fxp(4) drops driver lock in Rx path so check the fxp(4) is still
running after reacquiring driver lock in Rx path. Also don't
invoke fxp_intr_body if fxp(4) is not running. With this change
there is no need to set suspend bit in device attach phase.
hardware reset in attach phase. Selective reset does not clear
configured parameters so I think full hardware reset is required.
To prevent PCI bus lock-up, do selective reset first which will get
off the controller from PCI bus and request software reset after
selective reset. Software reset will unmask interrupts so disable
it after the reset.
common mbuf dma tag for both Tx and Rx path but Rx buffer should
have single DMA segment and maximum buffer size of the segment
should be less than MCLBYTES.
fxp(4) also have to check Tx completion status which was updated by
DMA so we need BUS_DMASYNC_PREREAD and BUS_DMASYNC_POSTWRITE
synchronization in Tx path. Fix all misuse of bus_dmamap_sync(9) in
fxp(4). I guess this change shall fix occasional driver breakage in
PAE environments.
While I'm here add error messages of dma tag/buffer creation and
correct messages.
Intel agrees with my reading of the docs, make it so for all G4X chips.
The new register also has a 32 bit width as opposed to 24 bits. Fix
things up so that the counters roll over properly.

- remove mbuf iovec - useful, but adds too much complexity when isolated to
the driver
- remove driver private caching - insufficient benefit over UMA to justify
the added complexity and maintenance overhead
- remove separate logic for managing multiple transmit queues, with the
new drbr routines the control flow can be made to much more closely resemble
legacy drivers
- remove dedicated service threads, with per-cpu callouts one can get the same
benefit much more simply by registering a callout 1 tick in the future if there
are still buffered packets
- remove embedded mbuf usage - Jeffr's changes will (I hope) soon be integrated
greatly reducing the overhead of using kernel APIs for reference counting
clusters
- add hysteresis to descriptor coalescing logic
- add coalesce threshold sysctls to allow users to decide at run-time
between optimizing for forwarding / UDP or optimizing for TCP
- add once per second watchdog to effectively close the very rare races
occurring from coalescing
- incorporate Navdeep's changes to the initialization path required to
convert port and adapter locks back to ordinary mutexes (silencing BPF
LOR complaints)
- enable prefetches in get_packet and tx cleaning

rename ifq_attach/detach to ifq_init/ifq_delete to better identify

DP83065 Saturn Gigabit Ethernet controllers. These are the successors
of the Sun GEM controllers and still have a similar but extended transmit
logic. As such this driver is based on gem(4).
Thanks to marcel@ for providing a Sun Quad GigaSwift Ethernet UTP (QGE)
card which was vital for getting this driver to work on architectures
not using Open Firmware.

X = log2(oversampling factor).
- Lower down default filter oversampling factor from 128
(log2 = 7) to 32 (log2 = 5), saving worth of 80 Kb.
The use of better polynomial interpolator will raise
its conversion quality/accuracy to match (or slightly
better) with previous settings.
- Bump driver version.
coefficients quality:
- Linear interpolator for oversampling factor larger and equal
than 4096 (log2 = 12).
- Quadratic interpolator for oversampling factor larger and equal
than 256 (log2 = 8).
Default oversampling factor (128 ~ log2 = 7) will use OPT32X, which
provides better accuracy.
Characters between 0x07 and 0x0d are now also mapped, which means we can
display almost 256 different characters. Also remap certain types of
dashes and quotes, which means we can finally read our manual pages
without red question marks in them.

Add a small Unicode-to-CP437 remapping table to at least demonstrate
that the terminal emulator is perfectly capable of handling UTF-8. This
will of course break if the user loads a different font map, but it at
least allows people to give it a try.
I can now see the box drawing in dialog(1) and the arrows in mutt(1)
correctly.
