Description

The environment variables passed to --up scripts express the netmask differently for IPv4 and IPv6: for IPv4 you get

ifconfig_local=203.0.113.2
ifconfig_broadcast=203.0.113.255
ifconfig_netmask=255.255.255.0

but for IPv6 you get

ifconfig_ipv6_local=2001:DB80:0001::2
ifconfig_ipv6_netbits=64

The Linux network configuration tool ip wants to be told the netmask in /nn syntax for both IPv4 and IPv6. Calculating a /nn value from a dotted-quad netmask in a shell script is difficult. It would be nice, therefore, if we could have an ifconfig_netbits environment variable for IPv4.
