NAME
       decode_rs8 - Decode codeword (8bit data width)

SYNOPSIS
       int decode_rs8(struct rs_control * rs, uint8_t * data, uint16_t * par, int len, uint16_t * s, int no_eras, int * eras_pos, uint16_t invmsk,
		      uint16_t * corr);

ARGUMENTS
       rs
	   the rs control structure

       data
	   data field of a given type

       par
	   received parity data field

       len
	   data length

       s
	   syndrome data field (if NULL, syndrome is calculated)

       no_eras
	   number of erasures

       eras_pos
	   position of erasures, can be NULL

       invmsk
	   invert data mask (will be xored on data, not on parity!)

       corr
	   buffer to store correction bitmask on eras_pos

DESCRIPTION
       The syndrome and parity uses a uint16_t data type to enable symbol size > 8. The calling code must take care of decoding of the syndrome
       result and the received parity before calling this code. Returns the number of corrected bits or -EBADMSG for uncorrectable errors.
