MSVC issues the warning below:

../lib/cryptodev/rte_cryptodev.c(623): warning C4334: '<<':
    result of 32-bit shift implicitly converted to 64 bits
    (was 64-bit shift intended?)

The code would be better off by using 64 bit numbers to begin with.
That eliminates the need for a conversion to 64 bits later.
