struct rtllib_rxb *prxb = prxbIndicateArray[j];

struct rtllib_rxb {
        u8 nr_subframes;
        struct sk_buff *subframes[MAX_SUBFRAME_COUNT == 64];
        u8 dst[ETH_ALEN]; // here
        u8 src[ETH_ALEN]; // here
} __packed;

If I remember correctly - I missed it in the first version as well, but then 
added BUG into ether_addr_copy().
