That's a big improvement over "rx_num_evt". The first time I saw this 
struct, I thought I had to set rx_num_evt to the number of receiving AXR 
pins in use.

Maybe call it "rx_min_fifo_depth" because just "depth" might be 
interpreted as the capaciity or maximum size of the fifo, while in fact 
the parameter is a minimum amount of data to be put into the FIFO 
buffer. Of maybe "rx_fifo_thd" to indicate it's a threshhold. And use 
the same name for the "tx" part as well (tx_fifo_thd or tx_fifo_min_depth).
