Subject: [dpdk-dev] KNI PCIe number and VLAN Stripping
Date: Mon, 19 Mar 2018 10:10:41 +0900 (JST)	[thread overview]
Message-ID: <20180319.101041.604023037230225350.yasu@nttv6.jp> (raw)


Hi.

It is much appreciated if someone could answer the following questions.

1. Regarding KNI, what is the reasoning of giving the PCI device
number information when setting kni I/F ? Can the data be blank or
dummy ? I would like to create a virtual I/F inside my application
and its corresponding kni, which may not have the corresponding
physical PCIe slot. 

2. the ETHER/VLAN/ARP packet looks not-supported both
in mbuf_ptype(RTE_PTYPE_XXX in m->packet_type) and
in PKT_RX_VLAN_STRIPPED situation.
  2a. How can we encode in m->packet_type to indicate there are
      arp_hdr after the (ether_hdr,vlan_hdr) pair ?
  2b. How can we get the next header value (i.e. ether_proto in
      vlan_hdr) when the vlan_hdr is stripped by the NIC ?

Thanks in advance.

Best regards,
Yasu
