[Tinyos Core WG] Meeting: 3/19

[Jan Hauer]

We missed the call (due to daylight-saving time), but then had a short
internal discussion on TEP125: a 802.15.4 header can vary between 3
and 23 byte in length (up to 37 with security), but in the current
T-Frame/I-Frame CC2420 implementation we expect a 15.4 header with a
specific length (9 byte) and a specific format. If we want to stick to
static header sizes then the "802.15.4 Header" part of T-Frame/I-Frame
should be exactly specified. The drawback is that we then lose general
interoperability with 6lowpan networks. Alternatively if we allow
dynamic 15.4 header sizes then, e.g. the cc2420_header_t would
probably need to allocate the maximum size, which in turn means that
message_t gets "bloated". Comments ?
