27/* GSM EFR - subjective importance bit ordering */
28 /* This array encodes GSM 05.03 Table 6.
29 *
30 * It converts between serial parameter output (as described in
31 * GSM 06.60 Table 6 and GSM 05.03 Table 5) and the order needed
32 * before channel encoding. CRC poly and bit repetition must be
33 * applied prior to this table, as in GSM 05.03 3.1.1, to get 260
34 * bits from a 244 bits raw EFR frame.
