When a packet is received and all Rx buffers are full, the variable RxBank is left with its pre-initialized value of 0xFF.
The RxBank variable was then used as an array index into a buffer array of BANK_SIZE elements.
The error code value of uint8_t 0xFF used as an array index causes packet data to be written far outside the memory allocated
for the buffer table of BANK_SIZE elements (4 elements).
