for the AN985 "Centaur" chip, which is apparently the next genetation
of the "Comet." The AN985 is also a tulip clone and is similar to the
AL981 except that it uses a 99C66 EEPROM and a serial MII interface
(instead of direct access to the PHY registers).
Also updated various documentation to mention the AN985 and created
a loadable module.
I don't think there are any cards that use this chip on the market yet:
the datasheet I got from ADMtek has boxes with big X's in them where the
diagrams should be, and the sample boards I got have chips without any
artwork on them.
the Davicom DM9100 and DM9102 chipsets, including the Jaton Corporation
XPressNet. Datasheet is available from www.davicom8.com.
The DM910x chips are still more tulip clones. The API is reproduced
pretty faithfully, unfortunately the performance is pretty bad. The
transmitter seems to have a lot of problems DMAing multi-fragment
packets. The only way to make it work reliably is to coalesce transmitted
packets into a single contiguous buffer. The Linux driver (written by
Davicom) actually does something similar to this. I can't recomment this
NIC as anything more than a "connectivity solution."
This driver uses newbus and miibus and is supported on both i386
and alpha platforms.
SiS 900 and SiS 7016 PCI fast ethernet chipsets. Full manuals for the
SiS chips can be found at www.sis.com.tw.
This is a fairly simple chipset. The receiver uses a 128-bit multicast
hash table and single perfect entry for the station address. Transmit and
receive DMA and FIFO thresholds are easily tuneable. Documentation is
pretty decent and performance is not bad, even on my crufty 486. This
driver uses newbus and miibus and is supported on both the i386 and
alpha architectures.
I backed-out the changes in -current and didn't touch stable at all (I
thought I had my patch order reversed, not what actually happened).
AIEEE! I can't even blame the crack for this one since I broke my
crack pipe a few weeks ago. I think sleep deprivation gets the blame
for this one.
Medal for noticing this one goes to: Jim Bloom <bloom@acm.org>
bringing in DHCP support. The only thing I left out were Poul-Henning's
newfs changes since I'm not sure if he's brought the rest of that support
into -stable yet. If it turns out that this is the case, I'll MFC those
changes too.
PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)
This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.
The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.
in a previous FreeBSD version. That never happened. Document that
it is due to be replaced, but leave it open-ended as to when.
Also do some mdoc cleanup.
