Date: Tue, 01 Jul 2014 12:14:53 -0700 (PDT) From: David Miller <davem@...emloft.net> To: zoltan.kiss@...rix.com Cc: steffen.klassert@...unet.com, minipli@...glemail.com, dborkman@...hat.com, tgraf@...g.ch, joe@...ches.com, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, xen-devel@...ts.xenproject.org Subject: Re: [PATCH net-next] pktgen: Allow setting frag sizes individually From: Zoltan Kiss <zoltan.kiss@...rix.com> Date: Wed, 25 Jun 2014 21:42:51 +0100 > 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 <zoltan.kiss@...rix.com> Can you respin these against current net-next and repost, thanks Zoltan. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
