> The union iavf_32byte_rx_desc consists of two unnamed structs defined inside.
> One of them represents legacy 32 byte descriptor and second the
> 16 byte descriptor (extended to 32 byte). Each of them consists of bunch of
> unions, structs and __le fields that represent specific fields in descriptor.
> 
> This commit changes the representation of iavf_32byte_rx_desc union to store
> four __le64 fields (qw0, qw1, qw2, qw3) that represent quad-words. Those quad-
> words will be then accessed by calling leXY_get_bits macros in upcoming
> commits.
