From: Xiaoyu Min Date: Wed, 17 Jul 2019 12:27:08 +0000 (+0800) Subject: app/testpmd: support raw encap/decap actions X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=30626def03d6a6f014c327341a9d122a8b901c06;p=dpdk.git app/testpmd: support raw encap/decap actions This patch intend to support action_raw_encap/decap [1] in a generic and convenient way. Two new commands - set raw_encap, set raw_decap are introduced just like the other commands for encap/decap, i.e. set vxlan. These two commands have corresponding global buffers which can be used by PMD as the input buffer for raw encap/decap. The commands use the rte_flow pattern syntax to help user build the raw buffer in a convenient way. A common way to use it: - encap matched egress packet with VxLAN tunnel: testpmd> set raw_encap eth src is 10:11:22:33:44:55 / vlan tci is 1 inner_type is 0x0800 / ipv4 / udp dst is 4789 / vxlan vni is 2 / end_set testpmd> flow create 0 egress pattern eth / ipv4 / end actions raw_encap / end - decap l2 header and encap GRE tunnel on matched egress packet: testpmd> set raw_decap eth / end_set testpmd> set raw_encap eth dst is 10:22:33:44:55:66 / ipv4 / gre protocol is 0x0800 / end_set testpmd> flow create 0 egress pattern eth / ipv4 / end actions raw_decap / raw_encap / end - decap VxLAN tunnel and encap l2 header on matched ingress packet: testpmd> set raw_encap eth src is 10:11:22:33:44:55 type is 0x0800 / end_set testpmd> set raw_decap eth / ipv4 / udp / vxlan / end_set testpmd> flow create 0 ingress pattern eth / ipv4 / udp dst is 250 / vxlan vni is 0x1234 / ipv4 / end actions raw_decap / raw_encap / queue index 1 / mark id 0x1234 / end [1] http://mails.dpdk.org/archives/dev/2018-October/116092.html Signed-off-by: Xiaoyu Min Reviewed-by: Ferruh Yigit --- diff --git a/app/test-pmd/cmdline.c b/app/test-pmd/cmdline.c index f7eb8a7776..11801769a0 100644 --- a/app/test-pmd/cmdline.c +++ b/app/test-pmd/cmdline.c @@ -1138,6 +1138,12 @@ static void cmd_help_long_parsed(void *parsed_result, " eth-src (eth-src) eth-dst (eth-dst)\n" " Configure the NVGRE encapsulation for flows.\n\n" + "set raw_encap {flow items}\n" + " Configure the encapsulation with raw data.\n\n" + + "set raw_decap {flow items}\n" + " Configure the decapsulation with raw data.\n\n" + );
