At present, the following hwsim test cases utilize puncturing, but the bitmap is not sent to the kernel. Instead, the puncturing information is conveyed only through the beacon data: * eht_5ghz_80mhz_puncturing_override_1 * eht_5ghz_80mhz_puncturing_override_2 * eht_5ghz_80mhz_puncturing_override_3 A future change in hostapd will begin configuring the puncturing bitmap explicitly, which will cause these test cases to fail unless the driver advertises support. To address this, update mac80211_hwsim driver to advertise puncturing feature support.
