Hi Murali,

The issue could be related to l2fwd trying to load enic poll mode driver
instead of oce driver.

>From your output I see ...

PMD: ENICPMD trace: rte_enic_pmd_init

ENIC is a Cisco Network Driver and you should be have something like
rte_oce_pmd_init

Can you check id table (vendor id/device id) in your OneConnect poll mode
driver ?

Thanks
Krishna

Thanks Krishna and Vladimir.



I am able to run l2fwd app with our Emulex PMD oce driver using –d Add
driver option



./l2fwd -c f -n 2 -d /DPDK2/librte_pmd_oce.so -- -q 1 -p 0x3

Murali

Hi All,



I am unable to run l2fwd app on linux, due to ‘Cause: No Ethernet ports -
bye' error



I am using *DPDK 2.0.0* with *Emulex OCe14102* adapter

Options:
    --help, --usage:
        Display usage information and quit

    --status:
        Print the current status of all known network interfaces.
        For each device, it displays the PCI domain, bus, slot and function,
        along with a text description of the device. Depending upon whether the
        device is being used by a kernel driver, the igb_uio driver, or no
        driver, other relevant information will be displayed:
        * the Linux interface name e.g. if=eth0

        * any suitable drivers not currently using that device

        NOTE: if this flag is passed along with a bind/unbind option, the status

    -u, --unbind:
        Unbind a device (Equivalent to \"-b none\")

    --force:
        By default, devices which are used by Linux - as indicated by having
        routes in the routing table - cannot be modified. Using the --force
        flag overrides this behavior, allowing active links to be forcibly
        unbound.
        WARNING: This can lead to loss of network connection and should be used
        with caution.

Examples:
---------

To display current device status:

To bind eth1 from the current driver and move to use igb_uio
        %(argv0)s --bind=igb_uio eth1

To unbind 0000:01:00.0 from using any driver
        %(argv0)s -u 0000:01:00.0
