Values 01 and 10 indicate advanced AxC mapping modes in which
each MAP interface can implement a different channel rate and
radio standard.

Index for configuring antenna-carrier interface information
in the advanced mapping Rx and Tx tables. The value in this
field determines the table entries that appear in the
CPRI_MAP_TBL_RX and CPRI_MAP_TBL_TX registers.
MAP interfaces use the same sample rate, as described in
the CPRI V4.1 Specification sections 4.2.7.2.2 and
4.2.7.2.3).
Method 1: IQ sample based.
Method 3: Backward compatible.
