Subject: [PATCH] devinet: show all addresses assigned to interface


Not all ips are shown by "ip addr show" command when IPs number assigned to an
interface is more than 60-80 (in fact it depends on broadcast/label etc
presence on each address).

Steps to reproduce:
It's terribly simple to reproduce:

# for i in $(seq 1 100); do ip ad add 10.0.$i.1/24 dev eth10 ; done
# ip addr show

this will _not_ show all IPs.
Looks like the problem is in netlink/ipv4 message processing.

This is fix from bug submitter, it looks correct.
