Hi fellows!
  
  I've a home network with an OpenBSD box as default gateway for my LAN. This 
box have 2 interfaces, xl0 (LAN) and ne3 (dhcp/cablemodem). IPF & NAT rules 
are in place and everything is working fine, but.. Can someone explain me 
this warning?

-Oct  5 06:40:23 gateway /bsd: ne3: warning - receiver ring buffer overrun-


here's my configuration:

gateway# uname -a
OpenBSD gateway 2.9 GENERIC#653 i386
gateway# ifconfig -a
[...]
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: Ethernet autoselect (100baseTX)
        status: active
        inet X.X.X.X netmask 0xffffff00 broadcast X.X.X.X
[...]
ne3: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        media: Ethernet autoselect (10baseT)
        inet X.X.X.X netmask 0xffffff00 broadcast X.X.X.X
