How can I stop "discard oversize frame" errors?

[Bryan Albright]

G'day all--

I just had to recreate my home machine (HD died) and in doing so, I
took the plunge to go from FreeBSD 4.11 to FreeBSD 5.4

I've cvsup-ed and re-made my world yesterday (Thursday) but now, I'm
getting this error message, admittedly only when I do a samba mount,
(yes, even using a generic smb.conf:
[global]
workgroup = MYHOMEGROUP
security = SHARE
[Plans]
path = /plans
read only = Yes
guest ok = Yes
)

fxp0: discard oversize frame (ether type 800 flags 3 len 1573 > max 1514)
fxp0: discard oversize frame (ether type 800 flags 3 len 1533 > max 1514)
fxp0: discard oversize frame (ether type 5555 flags 3 len 1520 > max 1514)
fxp0: discard oversize frame (ether type 800 flags 3 len 1564 > max 1514)

I have 2 NICs in my machine, both intel etherexpress pro:

%  pciconf -l | grep fxp
fxp0 at pci1:7:0:  class=0x020000 card=0x000a8086 chip=0x12298086 rev=0x05 hdr=0x00
fxp1 at pci1:10:0: class=0x020000 card=0x000b8086 chip=0x12298086 rev=0x08 hdr=0x00

I have fxp1 set to my internal network, and fxp0 set to connect to my
router.  My FreeBSD box is set up as a DNS server, Firewall, Router,
Web-cache-ing server, and quick-n-easy parental control filter (for my
kids).

I have 'gateway_enable="YES"' in my rc.conf, and it forwards the
packets correctly.

I'm using IPFW, enabled in the kernel:
options         IPFIREWALL
options         IPFIREWALL_VERBOSE
options         IPFIREWALL_VERBOSE_LIMIT=5
options         IPFIREWALL_DEFAULT_TO_ACCEPT
options         IPDIVERT


What else can I provide to help diagnose and fix what is causing this?

Thanks!

Bryan
