pcap file

Tommaso noticed a strange thing when debugging some code. 
If we run wifi-simple-infra, the wifi management packets in the PCAPs are all marked as wrong by Wireshark.
Pcap is in attachment.

This seems to be an old bug or it is a wireshark issue.

Comment 2 sebastien.deronne 2017-07-11 14:59:48 UTC

This is well a ns-3 bug. This is related to a HT Control field that should not be present here. I will work on a fix.

This was because the order bit was set, indicating Wireshark that HT Control field should be printed.
