6875d25465 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

75c66a120a if_sr.c corrupted the global variable `ticks'.
Cosmetic changes:
if_sr_.c won't compile with a K&R compiler, so there is no need to cast
the timeout arg to the (wrong) type.

c2b3cc824d Remove some unnecessary code in the interrupt handler.
Check that a received packet isn't longer than MCLBYTES. This will
sometimes happen if a cable is plugged into or removed from a live
system.
Try to cater better for early receive interrupts.

bfbb029d87 Remove devconf, it never grew up to be of any use. 1996-09-06 23:09:20 +00:00

c673fe98d7 Added #include of <machine/md_var.h>. This will be needed when
some declarations are moved from <machine/cpufunc.h> to better
places.

d80101ee8e Improve the handling of receive errors. Fix a nasty bug in the receive
buffer code.

fe63158271 Changes to the Digi/Arnet SYNC driver:
1. Create 2 x 8k transmit buffer blocks in place of the 16k block previously.
   With this change the speed as tested with ttcp on a 2Mbit link went up
   from 206kbyte/s to 236kbyte/s.
2. Change the rest of the functions to also have the definition of the
   return value on a sepperate line.
3. Remove some unused variables.
4. Add code to recover from DMA underruns.
5. Reorder ar_get_packets() to handle errors better.
6. Only allocate a mbuf cluster if the data is more than the mbuf.

(and in a second diff in addition to the above)
7. Stops the occasional DMA underruns that occurred when 2 channels
   are running at 2Mbit/s.

af6646cdc5 Make the handshake lines do the right thing. This is untested by the author
but others say it's working. (DTR etc)

9b44ff2214 Clean up Ethernet drivers:
- fill in and use ifp->if_softc
	- use if_bpf rather than private cookie variables
	- change bpf interface to take advantage of this
	- call ether_ifattach() directly from Ethernet drivers
	- delete kludge in if_attach() that did this indirectly

4a5f1499b0 all:
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.

if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.

if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).

cc9fce5ad7 This driver supports the Arnet SYNC/570i ISA cards that is based on the
HD64570 chip. Both the 2 and 4 port cards is supported and auto detected.

Line speeds of up to 2Mbps is possible. At this speed about 85% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the V.35 and X.21 interfaces is supported. The others
may need tweaks to the clock selection code.
