You can also set the mtu on your wifi devices higher (and bat0 devices). So for example wifi device to 1524 and bat0 to 1500 (like the eth devices). Also check if you have bridge mtu patch from Simon[1] (included in linux 2.6.27) when you are bridging some of the devices. Also check that icmp "Destination Unreachable" - "Fragmentation required, and DF flag set" isn't filtered anywhere.

The Linux workstations are attached via Ethernet, running Ubuntu.
The MTU, by default, is 1500 on eth0, ath0, wifi0 The MTU, by default, is 1476 on bat0, br-lan
Ping from Linux workstation to Linux workstation works as long as the -s flag is 1448 or less. 1448 = 1476 - 28 The -M do doesn't seem to change anything.
HTTP transfers still don't go through when they are larger than ~1400 bytes. I'll go play with the MTUs now.
Ok, setting mtu of ath0's to 1524 and of bat0 to 1500 should help here. Just for the sake of completeness: Is there bridging involved in the workstations or any icmp filtering on the workstations/nanostations?
