the OS does FXSAVE/FXRESTOR instructions (fast FPU save/restore) during
context switching and also enables SIMD since this enables saving the
extra CPU context that isn't saved with normal FPU regs. The other
enables the SIMD instructions to use exception 16 (FPU) error reporting.
Note, this doesn't turn on SIMD, just defines the bits.

:If an incoming connection is initiated through natd and deny_incoming is
:not set, then a new alias_link structure is created to handle the link.
:If there is nothing listening for the incoming connection, then the kernel
:responds with a RST for the connection. However, this is not processed
:correctly in libalias/alias.c:TcpMonitor{In,Out} and
:libalias/alias_db.c:SetState{In,Out} as it thinks a connection

:If many of these half-connections are initiated (during, for example, a

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.
this PHY and the Davicom DM9101 have exactly the same register definitions.
One of them is probably a clone of the other. I'm not sure which.

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.

1. Move definitions of struct i386_*_args to the header file sysarch.h,
since they are part of the sysarch API. struct i386_get_ldt_args and

struct i386_ldt_args. Libc should use these definitions as well.

external NatSemi PHY chip was programmed to respond to MII address 24.
In the 3c905B ASICs, the transceiver is internal but it's still mapped
to MII address 24. But *some* 3Com 3c905B ASIC revisions map the
transceiver control registers to *all* MII addresses (0 through 31).
The miibus code probes for PHYs at all MII addresses and because of
this unusual behavior, it will attempt to map the same PHY registers
several times over, which doesn't work.
Naturally, the 3c905B NIC that I tested happened not to exhibit this
behavior.
The fix is to tweak xl_miibus_readreg() and xl_miibus_writereg()
to only respond when attempting to read from MII address 24. This
is safe to do since the 3Com documentation indicates that the PHY
and/or internal transceiver will always be mapped to address 24,
and there are no 3Com XL NICs with more than one PHY.

statement to put the rcsid into the .comment section. This allows
the comments (ie:version id's of compiler, headers, source, etc) to be

Using __attribute__((section(".comment"))) would probably also work,

due to the fact that there are non-MII cards supported by the same
driver and I don't have all of the cards available for testing. There's
also the 3c905B-COMBO which has MII, AUI and BNC media ports all in one
package. Supporting the COMBO is difficult because we have to add the
10base5 and 10base2 media types to the same ifmedia struct as the
MII-attached types, however there is no way to force the miibus and
child PHYs into existence before xl_attach() completes, so there is
no ifmedia struct available in xl_attach(). What we do inistead is
use the mediainit method as a callback: when a child PHY is attached,
it calls the miibus mediainit routine which selects a default media.
This routing also calls the NIC driver's mediainit method (if it
implements one) at which point we can safely add the other media
types.
ones were made by Lucent). The Broadcom chip also appears to use an
internal PHY made by Broadcom which uses the Broadcom OUI. This is different
from previous ASICs which always returned 0 in the PHY ID registers.
To account for this, I added the necessary ID values for the Broadcom
PHY so that it can be detected and attached using the 3Com PHY driver
instead of defaulting to the generic one.

This fixes, at least, panics in ncr_attach() on i386's with about 5MB

restriction did was cause our allocations to fail when there is no free
memory above 1MB.
some swapper problems analogous to those experienced with ccd.
This fix is a kludge: since we currently don't track the "sector size"
in a volume label, we guess a worst case (4 kB, as used by vnode
devices). If the concept of sector size is here to stay, I'll make
some changes to track the "sector size" of a volume. This will
probably be the maximum of the sector sizes of all component drives,
but things could get ugly if we start allowing non-standard sector
sizes such as 524 bytes.
