2019-04-08	Update MCS selection for retransmission	Max	1	-0/+1
	In 3GPP TS 44.060 the selection of MCS for retransmissions is defined as separate tables (8.1.1.1 and 8.1.1.2) depending on the value of resegmentation bit (which is opposite to the way EGPRS_ARQ are defined in the source code). Let's follow the same idea and explicitly check for resegmentation bit value and use separate tables. This also makes it easier to add proper support for special cases (MCS-6-9 and MCS-5-7) and padding in future independently for different ARQ types. The code is also moved to c to avoid unnecessary conversions to and from cpp class. Change-Id: Ia73baeefee7a58834f0fc50e3b8bf8d5e3eb7815
2019-03-27	MCS: add Channel Coding Command encoder	Max	1	-0/+2
	Add function to encode MCS value as proper EDGE or GPRS Channel Coding value according to 3GPP TS 44.060 and corresponding helpers. Use it for everything except IA Rest Octet encoding which is done in a follow-up patches to make sure that we distinguish between encoding-related changes to test output and unrelated changes.

2019-03-26	MCS: add mcs_is_*() helpers	Max	1	-0/+4
	In preparation for Channel Coding Command encoder in follow-up patches let's add necessary helpers. Those are similar to previously used helpers from GprsCodingScheme class but without CamelCase and with less typo chances between Gprs and Egprs cases.

2019-03-24	MCS: move Mode enum outside of class definition	Max	1	-0/+8
	Move Mode (EDGE/GPRS) definition and related functions outside of GprsCodingScheme class. This allows us to use standard libosmocore value_string functions. Change-Id: I3baaac7f1ca3f5b88917a23c1679d63847455f47
2019-03-19	MCS: use value_string for conversion	Max	1	-0/+5
	Change-Id: I212ebb892ab162821633974d5a6c7e315d308370
2019-03-19	MCS: move HeaderType enum outside of class definition	Max	1	-0/+17
	Move functions which compute number of blocks or bits depending on header type and corresponding enum outside of GprsCodingScheme class. This will allows us to use standard libosmocore value_sting functions in upcoming patches for IA Rest Octet encoding/decoding. Change-Id: Id0873f85e1f16a72e17e7fbc4ad76b194917067f
2019-03-12	MCS: move Coding Scheme enum outside of class definition	Max	1	-0/+29
	Move generic MCS enum to C header file to simplify further modifications to GprsCodingScheme class in follow-up patches. This also allows us to use standard libosmocore value_sting functions in upcoming patches for IA Rest Octet encoding/decoding. Related: OS#3014 Change-Id: I993b49d9a82b8c7ad677d52d11003794aeabe117
