    i40e/i40evf: organize and re-number feature flags · b74f571f
    Jacob Keller authored
    Now that we've reduced the number of flags, organize similar flags
    together and re-number them accordingly.
    
    Since we don't yet have more than 32 flags, we'll use a u32 for both the
    hw_features and flag field. Should we gain more flags in the future, we
    may need to convert to a u64 or separate flags out into two fields.
    
    One alternative approach considered, but not implemented here, was to
    use an enumeration for the flag variables, and create a macro
    I40E_FLAG() which used string concatenation to generate BIT_ULL values.
    This has the advantage of making the actual bit values compile-time
    dynamic so that we do not need to worry about matching the order to the
    bit value. However, this does produce a high level of code churn, and
    makes it more difficult to read a dumped flags value when debugging.
