Re: [dpdk-users] Unable to run l2fwd code

[Sagar Singha <singha.sagar09@gmail.com>]

I have found that it is failing in function "vmxnet3_dev_start()". when its
trying to activate the device by writing on BAR1 register and reading
from BAR1 register. after that only its failing.

        VMXNET3_WRITE_BAR1_REG(hw, VMXNET3_REG_CMD,
VMXNET3_CMD_ACTIVATE_DEV);
        ret = VMXNET3_READ_BAR1_REG(hw, VMXNET3_REG_CMD);

       /*=====================HERE IT IS FAILING AFTER READING THE
REGISTER===========*/
        if (ret != 0) {
                printf("============sagar:Device activation:
UNSUCCESSFUL==============`\n");
                PMD_INIT_LOG(ERR, "Device activation: UNSUCCESSFUL");
                return -EINVAL;
        }

any configuration issue ??
any solution please !!!!
