Hi,
When a new IP address shows up on an interface, the function
if_newaddr() save this IP address and its mask and boardcast address
into a data structure. If the corresponding IP mask or broad cast
address is not set, their data fields in this structure are bzero()-ed.
But, the code wipes the mask field if the broadcast address is not set
an leave the broadcast field untouched.
The diff below should fix this problem.
bye,
Jan
