fix pcap_write function
when use pcap cli to capture pcakets into two files rx01.pcap && rx02.pcap, the first time: 1)pcap rx trace on max 100 intfc any file rx01.pcap 2)......the process of capture data to buffer...... 3)pcap rx trace off the second time: 4)pcap rx trace on max 100 intfc any file rx02.pcap 5)......the process of capture data to buffer...... 6)pcap rx trace off the pcap_write function bug in this two lines pm->n_packets_captured = 0; if (pm->n_packets_captured >= pm->n_packets_to_capture) referring to calling pcap_close() will result in that the twice pcap cli both writes the packets into rx01.pcap, but nothing into rx02.pcap. Beside, the rx02.pcap file will not be created. solution: separate the pcap_close() out of pcap_write() Change-Id: Iedeb46f9cf0a4cb12449fd75a4014f95f3bb3fa8 Signed-off-by: Jack Xu <jack.c.xu@ericsson.com>
