> DSCP a.k.a L3 QoS is only supported on certain devices. To enforce
> this, this patch introduces a bitmap of features and helper functions.
>
> The feature bitmap is set based on device IDs on driver init.
> Currently, DSCP is the only feature in this bitmap, but there will be
> more in the future. In the DCB netlink flow, check if the feature bit is set
before exercising DSCP.
