Question about bridging code

[Fernando A. Paulo]

hi all,

this is about the thread regarding the use of a
freebsd bridge and tap(4) to change the contents
of the frames.

the solution proposed in the list was to use:

net.link.ether.bridge_cfg=fxp0:0,tap0:0,tap1:1,fxp1:1

then you'd write and application to bridge between
clusters 0 and 1.

i have a couple of questions, hopefully you can help
me:

1) wont the userland bridge kill your application
because of all the context-switches and copies?
 
2) are you using any library to rebuild your frames
(crc, etc)? i'm thinking about libnet.
 
i'd be very glad if you could help me with these
doubts.
 
thanks,
fernando.
