large enough to contain the ethernet header. There appears to be a
condition where the card can return "0" in some failure cases, and this
causes bad things to happen (a panic).
Fixed a bug in fxp_mdi_write - a hex number was missing a preceding 0x
and this was causing the routine to not wait for a PHY write to complete.
Added support for link0, link1, and link2 flags to toggle auto-
negotiation, 10/100, and half/full duplex:
link0 disable auto-negotiation
When set, these flags then have meaning:
-link1 10Mbps
link1 100Mbps
-link2 half duplex
link2 full duplex
...needs a manual page.
written:
1) Full duplex mode is now supported (and works!)
2) The 10Mbps-only PCI Pro/10 should now work (untested, however)
Thanks to Justin Gibbs for providing a PCI bus analyzer trace while the
Intel Windows driver was configuring the board...this made it possible
to figure out the mystery bit that I wasn't setting in the PHY for full
duplex to work.
Disabled the DMA byte counters - I had it this way originally and this is
the recommended setting.
Set crscdt to CRS only (0) since this is what it should be for an MII PHY.
Also fixed some comments.
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.
previous hackery involving struct in_ifaddr and arpcom. Get rid of the
abominable multi_kludge. Update all network interfaces to use the
new machanism. Distressingly few Ethernet drivers program the multicast
filter properly (assuming the hardware has one, which it usually does).
type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
testing for FXP_NTXSEG being reached in fxp_start()...just check for
non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().
<net/if_arp.h> and fixed the things that depended on it. The nested
include just allowed unportable programs to compile and made my
simple #include checking program report that networking code doesn't
need to include <sys/socket.h>.
not resuming the NIC as required for transmit. Thanks to Alan Cox
<alc@cs.rice.edu> for noticing this.
Added another performance optimization to compensate. :-)
Changed crscdt to 1...strange, but this seems to be needed for some reason
despite what the manual says.
ring that caused wrong things to happen sometimes.
Doubled the number of transmit descriptors to 128 so that the internal
FIFO in the NIC can be fully filled when dealing with small packets.
Several minor performance improvements.
to deal with the fact that we relied on devconf to do the shutdown
callouts in various drivers. The changes in this commit are to add support
for device shutdown in this driver via the new at_shutdown() mechanism.
Similar changes need to be made to all of the other drivers that need
a shutdown routine called (if_de.c comes to mind immediately).
- 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
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!).
