Subject: Re: [PATCH v2] doc: fix support table for ETH and VLAN flow items
Date: Fri, 14 Oct 2022 17:41:28 +0800 [thread overview]
Message-ID: <b7aeb1f4-be03-e526-7570-cd79e3ea12b0@huawei.com> (raw)
In-Reply-To: <20221013104849.2677995-1-i.maximets@ovn.org>
Hi Ilya,
I have some questions about has_vlan/has_more_vlan fields:
a\ DPDK framework support cvlan-tag(0x8100) and svlan-tag(0x88A8), and also deprecated qinq-tag(eg. 0x9100)
b\ If has_vlan is used, does it mean that all the VLAN tags(0x8100/88A8/9100) must be matched ?
I think this is different from using type, which can only match one of them.
c\ And has_more_vlan has the same function as has_vlan ?
d\ What the problems are solved by the new two fields?
If the above understanding is correct, and the hardware support identify there TPID(cvlan-0x8100, svlan-0x88A8, dqing-0x9100) as VLAN, then:
Rule: eth has_vlan is 1 / vlan vid is 100 / ipv4 / end actions xxx
Result: all ipv4 packets with at least one VLAN(the TPID can be one of the above) and the vid is 100 can be matched.
Rule: eth type is 0x8100 / vlan vid is 100 / ipv4 / end actions xxx
Result: all ipv4 packets with at lease one VLAN(which TPID must be 0x8100) and the vid is 100 can be matched.
Rule: eth has_vlan is 1 / vlan vid is 100 has_more_vlan is 1 / vlan vid is 200 / ipv4 / end action xxx
Result: all ipv4 packets with at least two VLAN(the TPID can be one of the above) and outer vid is 100 and the next vid is 200 can be matched.
Rule: eth type is 0x88A8 / vlan vid is 100 inner_type is 0x8100 / vlan vid is 200 / ipv4 / end action xxx
Result: all ipv4 packets with at least two VLAN(the first TPID is 0x88A8 and second TPID is 0x8100) and outer vid is 100 and the next vid is 200 can be matched.
Is the above result correct ?
Thanks
