            Bug ID: 537
           Summary: FM1000 "PMD: eth_fm10k_dev_init(): switch is not
                    ready" error
           Product: DPDK
           Version: 19.11
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org

  Target Milestone: ---

I am trying to run dpdk process on an fm10k NIC. I have configured dpdk to use
fm10k driver，and the NIC is successfully recognized.

I have bound the fm10k interface to use igb_uio driver and tried to run l2fwd
for testing.

I use the following command to run l2fwd:

./l2fwd -w 0000:05:00.0,enable_ftag=1 -w 0000:83:00.0,enable_ftag=1 -- -p 0x3

And sometimes the l2fwd gave me the following errors:

"PMD: eth_fm10k_dev_init(): switch is not ready"

I tried to add sleep and retry but it failed!
