wifi: nl80211: validate and configure puncturing bitmap
[ Upstream commit d7c1a9a0ed180d8884798ce97afe7283622a484f ]
- New feature flag, NL80211_EXT_FEATURE_PUNCT, to advertise
driver support for preamble puncturing in AP mode.
- New attribute, NL80211_ATTR_PUNCT_BITMAP, to receive a puncturing
bitmap from the userspace during AP bring up (NL80211_CMD_START_AP)
and channel switch (NL80211_CMD_CHANNEL_SWITCH) operations. Each bit
corresponds to a 20 MHz channel in the operating bandwidth, lowest
bit for the lowest channel. Bit set to 1 indicates that the channel
is punctured. Higher 16 bits are reserved.
- New members added to structures cfg80211_ap_settings and
cfg80211_csa_settings to propagate the bitmap to the driver after
validation.
