PCI fast ethernet adapters, plus man pages.
if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
various other PNIC devices
if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
other boards based on the Macronix 98713, 98713A, 98715, 98715A
and 98725 chips
if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
Rhine II chips (note: the D-Link and certain other cards
that actually use a Rhine II chip still return the PCI
device ID of the Rhine I. I don't know why, and it doesn't
really matter since the driver treats both chips the same
anyway.)
if_wb.c: Trendware TE100-PCIE and various other cards based on the
Winbond W89C840F chip (the Trendware card is identical to
the sample boards Winbond sent me, so who knows how many
clones there are running around)
All drivers include support for ifmedia, BPF and hardware multicast
filtering.
Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.
I also have a driver for the ASIX AX88140A in the works.
is completely empty. There is an interrupt for output completion. It
is painful to use, but polling method used in the corresponding fix in
sio.c (rev.1.152) can't be used because there is no status bit for
transmitter-empty. Now ttywait() works right.

Don't call timeout() for DTR wakeup if the relevant timeout is already
active. This fixes "timeout table full" panics when sufficiently many
cyopen()s are interrupted while they are sleeping waiting for the
timeout to expire.
cards. My machine didn't tickle this problem, so I can't tell if
it fixed anything or not. However, it didn't break my already working
1542-{B,C,CF,CP} probes.

were half of their physical offsets for ISA and 1/4 of their physical
offsets for PCI, while all other Cyclades offsets were physical/1 for
ISA and physical/2 for PCI. Logically wrong macros were used to scale
CY16_RESET and CY_CLEAR_INTR to the correct physical offsets.
Fixed some style bugs (mostly long lines).
use a 256 entry ring buffer of descriptersfor this purpose. This allows
the use of a simple 8bit counter in the sequencer code for tracking start
location.
Entries in the ring buffer now contain a "cmd_valid" byte at their tail.
As an entry is serviced, this byte is cleared by the kernel and set by
the sequencer during its dma of a new entry. Since this byte is the last
portion of the command touched during a dma, the kernel can use this
byte to ensure the command it processes is completely valid.
The new command format requires a fixed sized DMA from the controller
to deliver which allowed for additional simplification of the sequencer
code. The hack that required 1 SCB slot to be stolen for incoming
command delivery notification is also gone.
interrupt handlers. Instead, load and use it atomically as necessary.
This reduces mode switching overhead for "polled" mode interrupt handling
from 5 i/o's to 3 (per service type, per port) so that polled mode is only
slightly more inefficient than "interrupt" mode.
* Update drivers to the latest version of the bus interface.
The ISA drivers' use of the new resource api is minimal. Garrett has
some much cleaner drivers which should be more easily shared between
i386 and alpha. This has only been tested on cia based machines. It
should work on lca and apecs but I might have broken something.
If the next available mailbox is not in the free state, print a warning
and handle the condition as a temporary resource shortage. The condition
should never happen, but we shouldn't panic since recovery is possible.

Don't fail the probe if the illegal command bit is set in the status
register. If the BusLogic MultiMaster probe preceeded us, it may well
have determined that the card we are attaching to was not a true MultiMaster
by sending us a command that fails on the 154X.
Reset the adapter before doing the inquiry. This provides extra sanity
and will also clear the illegal command status bit that my be left over
from the MultiMaster probe.
truncated to 32 bits.
* Change the calling convention of the device mmap entry point to
pass a vm_offset_t instead of an int for the offset allowing
devices with a larger memory map than (1<<32) to be supported
on the alpha (/dev/mem is one such).
These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.
base register that controls Ultra-DMA, so we need to examine all possible
base registers instead of just giving up at the first empty one.
Also, looking at the source code to the BIOS, I see that they are also
checking for 0xffffffff as an invalid value so do the same. Stefan may like
to clean this up, but at least now I can find my PCI IDE registers.
the top half to do it.
Put in a dubious check for subdisk integrity when trying to bring
up a plex where others are already up. This particular kludge is
crying out for a rewrite of the whole state code.
Add code to set_plex_state and set_volume_state to defer updates when
called from an interrupt context. This doesn't happen yet, but it
could do.
