Description
As mtu related dropping of packets seems to be the biggest problem using batman-adv it is maybe a good idea to add a small section about it to the readme.
It should have following parts:
- Why mtu is lower for bat0
- Where packets are dropped in a typical scenario:
client brigded node1 bridged node2 server [eth0 (1500)] <-> [eth0 (1500) [eth0 (1500) <-> [eth0 (1500)] bat0 (1476)] bat0 (1476)] || || [wlan0 (1500)] <-> [wlan0 (1500)] - How it can be tested (
ping -M do -s 1472 $IP) - Effects on connections (hangs, connection loss, extreme slow tests with iperf
due to TCP window scaling going wild, ...) - What can be done against it (wlan0: mtu 1524; br0, eth0, bat0: mtu 1500)
- Effects of Simons PMTU bridge patch

There is fragmentation support now.
I don't know if we really need that anymore, but the ticket is pretty old, therefore i'm closing it.
