Display filters for AC parameters for different QOS access categories are missing in Wireshark 1.67 version

Hello,

In wireshark 1.2 version, we had display filters such as

wlan_mgt.wme.be.ac_param.ecwmin==7 or wlan_mgt.wme.bg.ac_param.txop_limit==$value

where it will filter out packets with ecwmin=7 in specific access category like BE/Voice/BG/Video.

In wireshark 1.67 or higher, this display filter for each Access category is not provided.

Instead they have just given a filter for each AC parameters common for all QOS access categories like below

wlan_mgt.wfa.ie.wme.acp.aci wlan_mgt.wfa.ie.wme.acp.aifsn wlan_mgt.wfa.ie.wme.acp.ecw.min wlan_mgt.wfa.ie.wme.acp.ecw.min

So we will not be able to filter the packets based on the each access category's AC parameters ?

Does anyone has a workaround or a solution for this issue ? Please suggest.
