>Description:
I have updated FreeBSD 4.2-R -> 4.6-S  and  4.3-R -> 4.6-S  (20020712) via NFS on two 
servers with four ethernet adaptors (4 fxp on one and 2fxp+ed+rl on other). And appear 
the problem with overfull traffic on third and fourth adaptors at a promiscuous mode 
(by tcpdump, arpwatch).For example:

 /kernel: fxp0: promiscuous mode disabled
 >netstat -I fxp0 -w 1
            input         (fxp0)           output

 The avarege is same.No problem.
 But on fxp2 and fxp3 I can see overfull traffic - maybe  whole traffic on ethernet.
 For example:
 /kernel: fxp1: promiscuous mode disabled
 >netstat -I fxp3 -w 1
             input         (fxp3)           output

 At promiscuous mode the traffic biggest.
 The same on second router on rl0 and ed0 (3rd and 4th adaptors).
 Whats the problem ???
 Sorry for my english.
