Typedef backend_options_t

typedef struct packed {

Backend option type:

• decouple_aw: AWs will only be sent after the first corresponding R is received

• decouple_rw: decouples the R and W channels completely: can cause deadlocks

• *_max_llen: the maximum log length of a burst

• *_reduce_len: should bursts be reduced in length?
