* [dpdk-dev] rte_mbuf's packet_type field @ 2016-03-01 17:15 Zoltan Kiss 2016-03-04 9:28 ` Olivier MATZ 0 siblings, 1 reply; 4+ messages in thread From: Zoltan Kiss @ 2016-03-01 17:15 UTC (permalink / raw) To: dev Hi, I have a quick question about this field: how do I know if the underlying PMD supports a particular protocol parsing. Let's say I want to check for SCTP packets, looking at this field tells me EITHER the packet is SCTP (or not), OR that the hardware has no idea about SCTP. Is there a way to figure that support out?

I guess you want to avoid to re-check all protocols in software if the hardware supports some of them and did not recognize them? In that case it may be interesting, but it would result in a lot of feature flags. Regards, Olivier ^ permalink raw reply [flat|nested] 4+ messages in thread

Nothing in the mainline, but there is a patches in-flight: http://dpdk.org/dev/patchwork/patch/10921/ Konstantin > > Regards, > Olivier ^ permalink raw reply [flat|nested] 4+ messages in thread
