[spp] 3 bugs for spp_pcap

[Hideyuki Yamashita]

Hi,

I found the following bugs for spp_pcap.

1. Some packets can not be captured after pcap start.

2. Packet drop happens when receiving 64 byte short packet on 10Gbps
wire rate.

3. On receiving pcap stop command, packets are not flushed to files.
So when repeat capturing without shutdown of spp_pcap,
old packets are included in the capture file.

I will fix those bugs and report patches to this ML.

Sorry for inconvenience.

BR,
