Hi Shawn,

Please note that these properties (with only one exception) were accepted long time ago
and are in use for the upstream powerpc platforms, eg:
$ git grep fsl,num_rx_queues
arch/powerpc/boot/dts/fsl/pq3-etsec2-0.dtsi:    fsl,num_rx_queues = <0x8>;
arch/powerpc/boot/dts/fsl/pq3-etsec2-1.dtsi:    fsl,num_rx_queues = <0x8>;
arch/powerpc/boot/dts/fsl/pq3-etsec2-2.dtsi:    fsl,num_rx_queues = <0x8>;
drivers/net/ethernet/freescale/gianfar.c:                       ret = of_property_read_u32(np, "fsl,num_rx_queues",

So, I think the bindings documentation could be added in a separate, follow-up, patch.

Thanks,
Claudiu
