+ * When only first split block is received bsn state
+ * will be set to EGPRS_RESEG_FIRST_SEG_RXD and when
+ * only second segment is received the state will be
+ * set to EGPRS_RESEG_SECOND_SEG_RXD. When both Split
+ * blocks are received the state will be set to
+ * EGPRS_RESEG_DEFAULT
+ * The EGPRS resegmentation feature allows MS to retransmit
+ * RLC blocks of HeaderType1, HeaderType2 by segmenting
+ * them to 2 HeaderType3 blocks(Example MCS5 will be
+ * retransmitted as 2 MCS2 blocks). Table 10.4.8b.1 of 44.060
+ * explains the possible values of SPB in HeadrType3 for UL
+ * direction. When the MCS is changed at the PCU, PCU directs the
+ * changed MCS to MS by PUAN or UPLINK ASSIGNMENT message along
+ * with RESEGMENT flag, Then MS may decide to retransmit the
+ * blocks by resegmenting it based on Table 8.1.1.1 of 44.060.
+ * The retransmission MCS is calculated based on current MCS of
+ * the Block and demanded MCS by PCU. Section 10.3a.4.3 of 44.060
+ * shows the HeadrType3 with SPB field present in it
