> 
> Change the MTU check with XDP to allow any supported value and only
> reject those outside of the range as opposed to rejecting any change when
> XDP is active. In situations where MTU size is not supported, return -EINVAL
> instead of -EPERM.
> 
> Add checks when enabling SRIOV, DCB, or adding L2FW offloaded device as
> they are not supported with XDP.
