Need more understanding so as to standardize the expected behavior.

The default value of "false" will NOT be backward compatible for devices that support Native WCMP.
The name of this attribute must be SAI_NEXT_HOP_GROUP_ATTR_DISABLE_NATIVE_WCMP with default value as False.

@erohsik Kishore, Can you please add comment that NOS should query this attribute as supported or not.
And only if supported then we should make the default as true i.e. native WECP.
If platform doesn't support this attribute then WECMP works just the way today it is.

When the SAI implementation repeats next hop group member entries, should the SAI_SWITCH_ATTR_AVAILABLE_NEXT_HOP_GROUP_MEMBER_ENTRY attribute be updated to reflect the count of the repeated entries, or should it be based on the number of unique members in the ASIC_DB?

Add new next hop group attribute to specify if a next hop group is programmed by repeating the next hop members in proportion to their weight or by using the intrinsic next hop group weight support in the hardware.
