CIDR calculation from netmask appears to be wrong

[Mart van de Wege]

Hi,

When calculating CIDR notation from the netmask (e.g. by instantiating an ipv4 network object), the function compute-cidr-prefix-from-netmask appears to return a wrong result. For example:

CL-USER> (sockets::compute-cidr-prefix-from-netmask (sockets:make-netmask :cidr 21))
11

Do I do something wrong, or is this function indeed counting from the wrong direction?
