Subject: [dpdk-dev] [PATCH v4 3/5] app/testpmd: update modify field flow action support
Date: Tue, 12 Oct 2021 13:49:17 +0300	[thread overview]
Message-ID: <20211012104919.13145-4-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20211012104919.13145-1-viacheslavo@nvidia.com>

The testpmd flow create command updates provided:

  - modify field action supports the updated actions
  - pointer type added for action source field
  - pointer and value source field takes hex string
    instead of unsigned int in host endianness

There are some examples of flow with update modified
field action:

1. IPv6 destination address bytes 4-7 assignment:
   0000::1111 - > 0000:xxxx:4455:6677::1111

   flow create 0 egress group 1
     pattern eth / ipv6 dst is 0000::1111 / udp / end
     actions modify_field op set
             dst_type ipv6_dst
	     dst_offset 32
             src_type value
             src_value 0011223344556677
	     width 32 / end

2. Copy second byte of IPv4 destination address to the
   third byte of source address:
     10.0.118.4 -> 192.168.100.1
     10.0.168.4 -> 192.168.100.1

   flow create 0 egress group 1
     pattern eth / ipv4 / udp / end
     actions modify_field op set
             dst_type ipv4_src
             dst_offset 16
	     src_type ipv4_dst
	     src_offset 8
	     width 8 / end

3. Assign METADATA value with 11223344 value from the
   hex string in the linear buffer. Please note, the value
   definition should follow host-endian, example is given
   for x86 (little-endian):

   flow create 0 egress group 1
     pattern eth / ipv4 / end
     actions modify_field op set
             dst_type meta
	     src_type pointer
	     src_ptr 44332211
	     width 32 / end

4. Assign destination MAC with EA:11:0B:AD:0B:ED value:

   flow create 0 egress group 1
     pattern eth / end
     actions modify_field op set
             dst_type mac_dst
	     src_type value
	     src_value EA110BAD0BED
	     width 48 / end
