Summary:                    broadcast address isn't recalculated if ifconfig of
a network address with a non-standard netmask
Description: 
There exist today an option CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS which
enables one to add a ifconfig argument like "broadcast +" which will
automatically
calculate broadcast address correctly.
If one don't add the broadcast address, it will be calculated by kernel
code in the ioctl of SIOCSIFBRDADDR. In the case the user sets a
non-standard
netmask, it will be calculated incorrectly (because the netmask isn't
known
at the time and standard netmask according to IP is used...)
The patch calculate and sets broadcast after setting netmask (but not
if broadcast has already been set -> we don't want to overwrite a already
specified broadcast) and thus this little nag is history :-)
