After the putback of CR 6667363 ndd ioctl logic can be handled in the GLDv3 layers in onnv build 90, nge ndd doesn't report adv_1000hdx_cap read/write capacity correctly.

The issue is that Brussels interface should extract these information from drivers to ndd. Further concern is that if a Fast Ethernet driver migrates to Brussels, showing their 1000fdx/hdx write capacities is explicit not proper.
