Add support for SPB handling for EGPRS UL TBF
This patch will modify the EGPRS UL TBF flow to support Split block
handling. This patch also contains test suite modification for SPB UL.
Scenarios like MCS6->MCS3, MCS4->MCS1, MCS5->MCS2, MCS9->MCS3
MCS7->MCS2, MCS8->MCS3 have been simulated and Integration tested
in NuRAN 1.0 hardware thoroughly. The scope of Unit testing is limited.
