If userspace provides a puncturing bitmap via the NL80211_ATTR_PUNCT_BITMAP attribute, the kernel with mac80211_hwsim driver currently rejects the command with the error: "driver doesn't support puncturing", because the driver does not advertise support for this feature. 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.
