Interesting. I've seen this before when testing the segmentation in hardware, but I assumed this was because of a problem in the segmentation implementation.

Actually looking further into it, I'm pretty sure this is caused by the segmentation implementation. In the current dev branch the maximum segment size is not set to the rxbufsize, which makes the segmenting fall back to the default 1 KiB. On the dev branch only bcast implements segmentation. This has been 'fixed' (the segmentation of broadcast is still broken) in #127, where the segment size is set correctly.
