ifconfig: 802.11: decode more information elements (IEs)

2025-06-09T21:44:26Z

Start dealing with Element ID Extension present (IE T=255) and start parsing elemants from the Element ID Extension set. Namely (partially) decode HE_CAPA, HE_OPER, MU_EDCA_PARAM_SET, and as well as SUP_OP_CLASS. For length reasons also rename UNKNOWN_ELEMID_%d to ELEMID_%d.

ifconfig: 802.11: factor out keyix printing

2025-06-09T21:44:25Z

The node unicast key (PTK) uses a key index of (-1) and printing a 64k number does not look great. Factor out printing the key number into a buffer and use 'ucast' for the node unicast key. Hope is that this will be useful for the future as well when we will have more/different keys possibly. Looks like (with -vk): AES-CCM 2:128-bit rsc 0 tsc 0 rx AES-CCM 3:128-bit rsc 0 tsc 0 rx AES-GCM ucast:128-bit rsc 0 tsc 0 tx+rx Sponsored by: The FreeBSD Foundation MFC after: 3 days Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D50555

ifconfig: 802.11: print node unicast key (PTK) if available in STA mode

2025-06-09T21:44:25Z

Add a variable when querying the BSSID so we can later use it rather than losing the "data" buffer. When printing key information also query the node unicast key if in STA mode (the key for the BSSID). Do not error in case we fail. This is helpful for debugging mostly; was also useful when testing GCMP support.

ifconfig: 802.11: also print IEEE80211_CIPHER_AES_GCM_128 information

2025-06-09T21:44:25Z

While we currently do not print the STA unicast key (PTK) we will not see this but it is for fullness and in preparations for follow-up hanges. Sponsored by: The FreeBSD Foundation MFC after: 3 days Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D50553

ifconfig: decode 256 bit CCM/GCM ciphers and 256 bit 802.1x/none keymgmt

net80211/ifconfig: swap IEEE80211_FVHT_USEVHT160 and 80P80

2025-02-15T15:49:02Z

ieee80211_setupcurchan() compares the flags in a greater than manner. In this case VHT160 should be > VHT80P80 as it is preferable. Swap the two flags and add a comment to note this.

Also hide the other vht options on -vht and only show vht40/80/160/80p80 when vht is enabled. While here fix some whitespace and comments. Sponsored by: The FreeBSD Foundation MFC after: 3 days Reviewed by: adrian, emaste Differential Revision: https://reviews.freebsd.org/D48326
