The idea of an application that handles bad packets is perfectly valid. Most applications don't want to see them, of course, but, conceptually, some applications would want to ask for bad packets because they are specifically designed to handle various networking problems including those that result in bad packets that the application can look at and report. Furthermore, it makes technical sense for DPDK to support such applications.

Having said that, I have no idea if that's why that field was added, and I don’t myself care if DPDK provides that feature in the future. I just thought I'd put the idea out there in case it makes any difference to you. If it were me, I'd probably decide it isn't hurting anything and not bother to remove it in case some day someone wants to implement that feature in one driver or another.
