Description
What I am specifically looking for is an option that existed in 2.3.5: -T Truncate packets > MTU so packets can be sent It would also be nice to have options such as:
-e <ip1:ip2> Specify IP endpoint rewriting
-I <mac> Rewrite dest MAC on primary interface
-J <mac> Rewrite dest MAC on secondary interface
-s <seed> Randomize src/dst IP addresses w/ given seed
These options provide a great degree of flexibility without the need to use cache files or tcprewrite to go through firewalls and routers.

Re-opening to track -T feature. Oops.
Note: -I/-J always did and still require a cache file to split traffic.

This fix might have some unexpected results, so here's what you need to know:
- If truncating IPv4 packets, then checksums (L3/L4) will be updated so that the packets appear valid
- All other cases, the packets are just truncated- no checksum updates

packet editing is available in 3.3.x/3.4.x when you use ./configure --enable-tcpreplay-edit as documented in the wiki & README.
In 3.4.1 onwards, there will be a separate tcpreplay-edit binary built (see #372)
