int mm
Bits per symbol
int nn
Symbols per block (= (1<<mm)-1)
uint16_t * alpha_to
log lookup table
uint16_t * index_of
Antilog lookup table
uint16_t * genpoly
Generator polynomial
int nroots
Number of generator roots = number of parity symbols
int fcr
First consecutive root, index form
int prim
Primitive element, index form
int iprim
prim-th root of 1, index form
int gfpoly
The primitive generator polynominal
int (*)(int) gffunc
Function to generate the field, if non-canonical representation
int users
Users of this structure
struct list_head list
List entry for the rs control list
