#181 pcap_read_linux_mmap does not respect timeout on first call
When pcap_read_linux_mmap is called (e.g. via pcap_next or pcap_next_ex) right after pcap_setfilter, it doesn't respect the timeout (i.e. sometimes it returns without a packet before the timeout occurs). This happens because the call to poll might not occur when packets that were in the packet ring before the filter was applied are skipped. The attached patch seems to fix this issue.
