ebtables & iptables

HI,ebtables-user


I am a newbei,i have some question.
1\if I used ebtables process a package,but need iptables can't process THIS package,how can I do?
2\i read the etables man page,in this:
  -p, --protocol [!] protocol 
     The protocol that was responsible for creating the frame. This can be a hexadecimal
     number, above 0x0600, a name (e.g. ARP ) or LENGTH. The protocol field of the Ethernet
     frame can be used to denote the length of the header (802.2/802.3 networks).  

how can I match the package LENGTH? can I mach : if the package > 128K then DROP?

thanks you help
(this mail is mail again,because i can't see it in maillist)
