hcxpcaptool does not detect beacon packet
#2
The timestamps are completely useless:
$ tshark -r hs_plus_beacon.pcapng -T fields -e frame.number -e frame.time

The merged pcapng file is a mixed header file:
DLT_IEEE802_11 (105)
DLT_IEEE802_11_RADIO (127).

Added support (hcxpcapngtool) for multiple interfaces by this commit:
https://github.com/ZerBea/hcxtools/commi...bbfdf54bc1

Code:
hcxpcapngtool -o test.22000 hs_plus_beacon.pcapng
reading from hs_plus_beacon.pcapng...

Warning: missing frames!
This dump file contains no important frames like
authentication, association or reassociation.
That makes it hard to recover the PSK.

Warning: missing frames!
This dump file contains no undirected proberequest frames.
An undirected proberequest may contain information about the PSK.
That makes it hard to recover the PSK.

Warning: missing frames!
This dump file doesn't contain enough EAPOL M1 frames.
That makes it impossible to calculate nonce-error-correction values.

Please keep in mind:
Neither EAPOLTIME calculation nor detection of nonce error correction will work on text2cap converted files, because we are missing original timestamps and multiple M1 frames.

Edit:
By latest commit hcxpcangtool is able to handle tv_nsec from this cap files, too.
