Hello Jenkins Builder,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#5).

csd_v110: handle TCH/F14.4
Thanks to the work done by Mychaela (see the related Change-IDs), we can finally implement handling of TCH/F14.4 (both T and NT modes) for osmo-bts-trx and osmo-bts-virtual.
This channel mode is special in a way that it employs a different rate adaptation function RAA' (defined in 3GPP TS 48.020 chapter 11), which converts between between 290-bit blocks used on Um and Abis-E1 interfaces (E-TRAU frames on the latter) and A-TRAU frames spoken over the A interface.
The result of function RAA' in the Uplink direction is 320 bits, which is equal to 4 x 80-bit V.110 frames, but actually carrying 8 x 36-bit packed frames. These 320 bits are then fed to the RA2 function, like we do for other CSD channel modes.
