the 802.3 frames generated by the DC21040 (which does automatic padding
of less-than-minimum frames) and the frames generated by the 'ed'
driver, I've found that there is indeed a bug in the size of "ETHER_MIN_LEN"
as reported by several people, John Hay being the most recent. The driver
was actually setting the length to 6+6+2+50 (64 bytes), which when adding
in the CRC (which is automatically appended to the frame and not included
in the length), the minimum frame is 4 bytes larger than it is supposed to
be. All of this is confirmed by tcpdump showing 50 bytes of data for
minimum frames from the 'ed' cards and 46 bytes from 'de' cards. This
analysis has also revealed that there is garbage in the un-filled in
portion at the end of the minimum frames from the 'ed' driver; I don't
plan to fix this.
require specific partitions be mentioned in the kernel config
file ("swap on foo" is now obsolete).
From Poul-Henning:
The visible effect is this:
As default, unless
options "NSWAPDEV=23"
is in your config, you will have four swap-devices.
You can swapon(2) any block device you feel like, it doesn't have
to be in the kernel config.
There is a performance/resource win available by getting the NSWAPDEV right
(but only if you have just one swap-device ??), but using that as default
would be too restrictive.
The invisible effect is that:
Swap-handling disappears from the $arch part of the kernel.
It gets a lot simpler (-145 lines) and cleaner.

A phone call from Manfred quickly pointed up the fact that I got the conflict
check backwards. NOW we implement the conflict checking correctly! Wheesh!
- Do the right thing when booting in NFS diskless mode, which is nothing.
Make the default unconfigured entries for swdevt[0] and dumplo something
that swapconf() will ignore and not choke on (the swap setup is done
in nfs_vfsops.c when booting diskless).
to access it. setdelayed() actually ORs the bits in `idelayed' into
`ipending' and clears `idelayed'.
Call setdelayed() every (normal) clock tick to convert delayed
interrupts into pending ones.
Drivers can set bits in `idelayed' at any time to schedule an interrupt
at the next clock tick. This is more efficient than calling timeout().
Currently only software interrupts can be scheduled.
boot diskless with it, you get a panic because setconf() is only
called for mountroot == ffs_mountroot. It really needs to be called
no matter what manner of rootfs we have. I can't really say if
swapgeneric will work with a CD-ROM though. (I get the feeling I'm
the only one who uses swapgeneric these days anyway.)
there may even be LKMs.) Also, change the internal name of `unixdomain'
to `localdomain' since AF_LOCAL is now the preferred name of this family.
Declare netisr correctly and in the right place.
It closed the wrong device (usually the B partition instead of the C
partition).
It closed a device without having opened it.
It didn't open a device often enough. This caused swap partitions on
slices other than the first slice looked at to be unavailable for swapping.
It didn't check the device number sufficiently.
Remove silly "Naffy, the Wonder Porpoise" attribution and add more
justifiable (and overdue) attribution to Bruce Evans. Look at it
as a delete and add operation batched together, not a substitution. :-)
notice, performed all of the structural changes necessary to get this thing
to work with the unidirectional-DMA version of voxware.
This work is -not- complete, but it's in far better shape than it was, and
I may not touch it again for another few months.
The ``flags 1'' in the fdc line is now only needed for owners of an
Insight tape (perhaps there aren't any? Mine is disfunctional). All
other probes are safe wrt. to the motor-control line of floppy disk
drives. Document the flag in LINT finally.
as side-effect, removed some legacy code that was necessary
when we called vm_fault inside of vm_fault_quick instead of using
the kernel/user space byte move routines.
