Subject: 40network: separate 'mask' and 'prefix'
|
|
|
|
The 'mask' parameter is used for both, the (IPv4) netmask and
|
|
the prefix length. As both are in different format separate them
|
|
out into 'mask' for the netmask and 'prefix' for the prefix length.
|
|
And also prefer the use of 'prefix' where possible to ease
|
|
calculation and better IPv6 support.
