i modified the bridge.c file and added a routine to

The modified kernel is deployed in network where the

continues data at 4 to 6 Mbps rather than sudden burst
at intervals.
Now the problem is, I am getting very high interrupts
from the network
interfaces. the cpu utilization by the interrupts is
high due to which there
is latency added to the packets forwarded by the pc.
The pc attempts to
compress/decompress all tcp packets.
Suggestion: start with a standard kernel, without your custom modifications.
If unmodified bridging works, and you get the high interrupt level, then you
have found a problem with in FreeBSD.
Or you have found that hardware using "rl" driver is not as good as some
other hardware. Read the source to get some more information.
