nfp: add DCB IEEE support
Add basic DCB IEEE support. This includes support for ETS, max-rate,
and DSCP to user priority mapping.
DCB may be configured using iproute2's dcb command.
Example usage:
dcb ets set dev $dev tc-tsa 0:ets 1:ets 2:ets 3:ets 4:ets 5:ets \
6:ets 7:ets tc-bw 0:0 1:80 2:0 3:0 4:0 5:0 6:20 7:0
dcb maxrate set dev $dev tc-maxrate 1:1000bit
And DCB configuration can be shown using:
dcb ets show dev $dev
dcb maxrate show dev $dev
