Fix 100% cpu usage when interface down. - ID: 2863204
Last Update: Settings changed ( guy_harris )
On some systems (distros, for example Archlinux, same messages I saw in
Ubuntu) there's problem with programs that uses libpcap. When interface
goes down it causes cpu usage to 100%. In libpcap there is no exception
statement about poll bitmasks when it return positive value. According to
'man poll' there is POLLHUP POLLNVAL and POLLERR which can be checked, also
in <bits/poll.h> there is POLLRDHUP defined for GNU systems. This patch
solves this problem.
