Subject: [dpdk-dev] [PATCH 1/2] app/testpmd: add portlist option to the testpmd
Date: Mon, 27 Jan 2020 10:30:52 +0000
Message-ID: <1580121053-26083-2-git-send-email-hariprasad.govindharajan@intel.com> (raw)
In-Reply-To: <1580121053-26083-1-git-send-email-hariprasad.govindharajan@intel.com>

    In current version, we are setting the ports
    using portmask. With portmask, we can use only
    upto 64 ports. This portlist option enables the user
    to use more than 64 ports.
    Now we can specify the ports in 2 different ways
    - Using portmask (-p [0x]nnn): mask must be in hex format
    - Using portlist in the following format
      --portlist <p1>[-p2][,p3[-p4],...]

    --portmask 0x2 is same as --portlist 1
    --portmask 0x3 is same as --portlist 0-1
