Hi people.

I noticed a ref to malformed packets back in 2002, but I have this problem
now, with a reasonably new hardware (CNAP 711 from CNet, with an
AT76C510 AP).

The packet is from a Trap, number 22, which is not documented in the
ATMEL-MIB that comes with the CD. It's apparently a time tick, each 5
seconds:

User Datagram Protocol, Src Port: snmp-trap (162), Dst Port: snmp-trap
(162) Simple Network Management Protocol
    Version: 1 (0)
    Community: public
    PDU type: TRAP-V1 (4)
    Enterprise: 1.3.6.1.4.1.12350.1.1
    Agent address: 192.168.0.254 (192.168.0.254)
    Trap type: ENTERPRISE SPECIFIC (6)
    Specific trap type: 22
    Timestamp: 59400

Can someone indicate what's wrong?
