The Rx descriptor word 2 keeps obsolete information for MAC translation. Therefore, these information bits
are undefined and should be ignored.

[31:0] NRXDSA
Next Rx Descriptor Starting Address
The Rx descriptor is a link-list data structure. Consequently, NRXDSA is
used to keep the starting address of the next Rx descriptor. The bits
[1:0] will be ignored by EMC. So, all Rx descriptor must locate at word
boundary memory address.
