Revision 1.63, Mon Mar 14 15:07:24 2022 UTC (2 years, 2 months ago) by stsp
Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, OPENBSD_7_3_BASE, OPENBSD_7_3, OPENBSD_7_2_BASE, OPENBSD_7_2, OPENBSD_7_1_BASE, OPENBSD_7_1, HEAD
Changes since 1.62: +90 -2 lines
Add initial 802.11ac (VHT) support to net80211.
Add VHT capability and operation IE definitions to ieee80211.h.
Introduce channel flags to identify 80MHz and 160MHz capable channels.
Parse VHT IEs in beacons, announce the driver's VHT capabilities in
probe requests and assoc requests, and hop into 11ac mode after
association to the AP if possible.
Enable VHT by default if the driver announces support for it.
