net/vmxnet3: return correct value for VMXNET3_CMD_GET_DEV_EXTRA_INFO
VMXNET3_CMD_GET_DEV_EXTRA_INFO should return 0 for emulation
mode
This behavior can be observed by the following steps:
1) run a Linux distro on esxi server (5.x+)
2) modify vmxnet3 Linux driver to read the register:
VMXNET3_WRITE_BAR1_REG(adapter, VMXNET3_REG_CMD, VMXNET3_CMD_GET_DEV_EXTRA_INFO);
ret = VMXNET3_READ_BAR1_REG(adapter, VMXNET3_REG_CMD);
pr_info("vmxnet3 dev_info: 0x%x\n", ret);
The kernel log will have some like the following message:
[ 7005.111170] vmxnet3 dev_info: 0x0
