Bill,
I think there is different syntax for this, I used to
use something like:
if(len_gt(max_len))
{
}
But, I don't check for max length any more. Operating system
assembly/disassembly for
packets bigger than the mtu is transparent to me, I often work with
big packets. Also,
the mtu is different depending on where you look. I think some of
the gig-ethernets
use jumbo packets, then there is the 1500 byte or so regular mtu,
then there
is also possible modifications to the mtu depending on what the local
transport is (cable,
dsl, frame relay, etc).
I still check for max hops :-)
