Thinking twice I am not sure if above change works. Since function is in the header file, and the .c file that assign the 'dev->rx_pkt_burst' and the .c file that check function pointer are different, these two different instance of same function may have different addresses and above check may fail when it should match. I guess solution is move the function to a .c file and export it internally. I was thinking to add ethdev_driver.c file, perhaps this can be a motivation to start that file. Thomas, Andrew, what do you think about ethdev_driver.c file?
