General issue report

according to https://wiki.wireshark.org/Development/LibpcapFileFormat#global-header the pcap header should be:

 typedef struct pcap_hdr_s {
            guint32 magic_number;   /* magic number */
            guint16 version_major;  /* major version number */
            guint16 version_minor;  /* minor version number */
            gint32  thiszone;       /* GMT to local correction */
            guint32 sigfigs;        /* accuracy of timestamps */
            guint32 snaplen;        /* max length of captured packets, in octets */
            guint32 network;        /* data link type */
    } pcap_hdr_t;

but the header specified here:

idf-extra-components/pcap/include/pcap.h

Line 52 in 116bceb

typedef struct {

doesn't include the magic number sigfigs, snaplen. ..
