Bridging Code - MAC Filtering

[Aldrin Leal]

Hello,

     Does the bridging code in FreeBSD 5.2-RELEASE have the hability
to perform mac checking for a given IP?

     If it doesn't, does any kernel hacker could point me to places
where i could do it myself? Maybe proper pointers on debugging the
bridging facilities, tips, general guidance and so forth?

      Thanks in advance!
