By defining the number of frags via "nfrags", their sizes get calculated by pktgen. This patch allows their offsets and sizes to be specified via "frag_off-len", in a comma separated list (e.g. "frag_off-len 0-1,500-200,5000-10,9-100). The first is the offset (0 <= offset < 2^16), second is size (0 < length <= 65536). This also determines the number of frags, so it overwrites "frags" (and vice versa, "frags" invalidate this setting) xen-netback is prone to have problem with compound pages, as the memory granting interface can only handle 4k pages. This extension of pktgen is proven to be useful to test that. Signed-off-by: Zoltan Kiss <redacted>
Can you respin these against current net-next and repost, thanks Zoltan.
