How can it be different of 64?
Using 64 would be simpler to understand than RTE_BIT_WIDTH_64.

Even your comment is saying that it
As 40G NIC supports different sizes (128/512/64 entries) of
redirection table from that (128 entries) of 1G and 10G NICs,
support of multiple sizes of redirection table is needed.
It includes,
* Redefine 'struct rte_eth_rss_reta' in ethdev.
- To 'struct rte_eth_rss_reta_entry64' which contains 64
