T

I did some compilation tests using `./build_oai -s --run-group "0101*"`, all was fine.

I ran `lte-softmodem` with the sequans and let it run for a while with both
uplink and downlink UDP low throughput traffic, all was fine.

I ran some TCP tests, downlink 14 Mb/s (because the sequans does not report
a CQI of 15 but 14 maximum, so we don't go to maximum MCS, so 14 Mb/s instead
of 16) with a very clean radio (almost no error in the HARQ processes).

For uplink things are not so clean, it starts at 6 Mb/s and after a while goes
down to 2/3 Mbit/s. Lot's of errors in the HARQ processes, mostly uplink but
also downlink.

This is a both with and without T activated.

So to me it's fine.

The T tracer is a debugging tool. When it's not enabled,
it has zero impact on the processing. I think we need to
do very little tests before merging. I'll let you decide
but to me it's okay!
