swapfile and tulip problems.

Firstly, swapfiles seem to be reusable:

dwmw2:/home/dwmw2 # swapon /swapfile
dwmw2:/home/dwmw2 # swapon /swapfile
dwmw2:/home/dwmw2 # swapon /swapfile
dwmw2:/home/dwmw2 # cat /proc/swaps
Filename Type Size Used Priority
/swapfile file 20476 0 -5
/swapfile file 20476 0 -4
/swapfile file 20476 0 -6
/swapfile file 20476 0 -7

Is this cosmetic, or is it really going to hate me if it ever fills what it
thinks is the first one and goes on to the next?

I noticed this because my RH 4.2 setup tries to mount the swap twice. Probably
the second is "mount -a".

Secondly, I periodically get complaints like this:
eth0: Ethernet frame spanned multiple buffers,status 0608858e!
eth0: Ethernet frame spanned multiple buffers,status 7fffceff!
eth0: Ethernet frame spanned multiple buffers,status 0605858e!
eth0: Ethernet frame spanned multiple buffers,status 7fffceff!
eth0: Ethernet frame spanned multiple buffers,status 0606858e!
eth0: Ethernet frame spanned multiple buffers,status 7fffceff!
eth0: Ethernet frame spanned multiple buffers,status 060a858e!

Just now, I got about 300 in quick succession. It's a brand new Kingston
KIN-40BT/1 tulip card, with support compiled into the kernel. I've not even
hacked the kernel about this time! Oh - wait a mo - yes I have, but only the
console stuff for an MDA screen.

Bus 0, device 19, function 0:
Ethernet controller: DEC DC21041 (rev 33).
Medium devsel. Fast back-to-back capable. IRQ b. Master Capable. Latency=32.
I/O at 0x6000 [0x6001].
Non-prefetchable 32 bit memory at 0xe1804000 [0xe1804000].

In the time it's taken me to compose this:
dwmw2:/var/log # tail -2000 messages | grep -c "Ethernet frame spanned"
1142

I'm going away for a couple of days; I think I'll kill klogd first. :)
