Introduce new NL attributes that are needed for enabling and configuring EDMG support. Two new attributes are used by kernel to publish driver's EDMG capabilities to the userspace: NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16 GHz channel(s) that are supported by the driver. When this attribute is not set it means driver does not support EDMG. NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth configurations supported by the driver. Additional two new attributes are used by the userspace for connect command and for AP configuration: NL80211_ATTR_WIPHY_EDMG_CHANNELS NL80211_ATTR_WIPHY_EDMG_BW_CONFIG New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver and used for bitrate calculation that will take into account EDMG according to the 802.11ay specification. --- drivers/net/wireless/ath/wil6210/cfg80211.c | 2 +- include/net/cfg80211.h | 86 ++++++++++++++- include/uapi/linux/nl80211.h | 24 +++++ net/mac80211/mlme.c | 2 +- net/mac80211/status.c | 2 +- net/wireless/chan.c | 159 ++++++++++++++++++++++++++++ net/wireless/nl80211.c | 37 +++++++ net/wireless/util.c | 42 +++++++- 8 files changed, 346 insertions(+), 8 deletions(-) diff --git a/drivers/net/wireless/ath/wil6210/cfg80211.c b/drivers/net/wireless/ath/wil6210/cfg80211.c index 2fb4258..2414f57 100644 --- a/drivers/net/wireless/ath/wil6210/cfg80211.c +++ b/drivers/net/wireless/ath/wil6210/cfg80211.c @@ -351,7 +351,7 @@ int wil_cid_fill_sinfo(struct wil6210_vif *vif, int cid, BIT_ULL(NL80211_STA_INFO_RX_DROP_MISC) | BIT_ULL(NL80211_STA_INFO_TX_FAILED); - sinfo->txrate.flags = RATE_INFO_FLAGS_60G; + sinfo->txrate.flags = RATE_INFO_FLAGS_DMG; sinfo->txrate.mcs = le16_to_cpu(reply.evt.bf_mcs); sinfo->rxrate.mcs = stats->last_mcs_rx; sinfo->rx_bytes = stats->rx_bytes; diff --git a/include/net/cfg80211.h b/include/net/cfg80211.h index 26e2ad2..616dfcd 100644 --- a/include/net/cfg80211.h +++ b/include/net/cfg80211.h @@ -318,6 +318,60 @@ struct ieee80211_sband_iftype_data { }; /** + * enum ieee80211_edmg_bw_config - allowed channel bandwidth configurations + * + * @IEEE80211_EDMG_BW_CONFIG_4: 2.16GHz + * @IEEE80211_EDMG_BW_CONFIG_5: 2.16GHz and 4.32GHz + * @IEEE80211_EDMG_BW_CONFIG_6: 2.16GHz, 4.32GHz and 6.48GHz + * @IEEE80211_EDMG_BW_CONFIG_7: 2.16GHz, 4.32GHz, 6.48GHz and 8.64GHz + * @IEEE80211_EDMG_BW_CONFIG_8: 2.16GHz and 2.16GHz + 2.16GHz + * @IEEE80211_EDMG_BW_CONFIG_9: 2.16GHz, 4.32GHz and 2.16GHz + 2.16GHz + * @IEEE80211_EDMG_BW_CONFIG_10: 2.16GHz, 4.32GHz, 6.48GHz and 2.16GHz+2.16GHz + * @IEEE80211_EDMG_BW_CONFIG_11: 2.16GHz, 4.32GHz, 6.48GHz, 8.64GHz and + * 2.16GHz+2.16GHz + * @IEEE80211_EDMG_BW_CONFIG_12: 2.16GHz, 2.16GHz + 2.16GHz and + * 4.32GHz + 4.32GHz + * @IEEE80211_EDMG_BW_CONFIG_13: 2.16GHz, 4.32GHz, 2.16GHz + 2.16GHz and + * 4.32GHz + 4.32GHz + * @IEEE80211_EDMG_BW_CONFIG_14: 2.16GHz, 4.32GHz, 6.48GHz, 2.16GHz + 2.16GHz + * and 4.32GHz + 4.32GHz + * @IEEE80211_EDMG_BW_CONFIG_15: 2.16GHz, 4.32GHz, 6.48GHz, 8.64GHz, + * 2.16GHz + 2.16GHz and 4.32GHz + 4.32GHz + */ +enum ieee80211_edmg_bw_config { + IEEE80211_EDMG_BW_CONFIG_4 = 4, + IEEE80211_EDMG_BW_CONFIG_5 = 5, + IEEE80211_EDMG_BW_CONFIG_6 = 6, + IEEE80211_EDMG_BW_CONFIG_7 = 7, + IEEE80211_EDMG_BW_CONFIG_8 = 8, + IEEE80211_EDMG_BW_CONFIG_9 = 9, + IEEE80211_EDMG_BW_CONFIG_10 = 10, + IEEE80211_EDMG_BW_CONFIG_11 = 11, + IEEE80211_EDMG_BW_CONFIG_12 = 12, + IEEE80211_EDMG_BW_CONFIG_13 = 13, + IEEE80211_EDMG_BW_CONFIG_14 = 14, + IEEE80211_EDMG_BW_CONFIG_15 = 15, +}; + +/** + * struct ieee80211_edmg - EDMG configuration + * + * This structure describes most essential parameters needed + * to describe 802.11ay EDMG configuration + * + * @channels: bitmap that indicates the 2.16 GHz channel(s) + * that are allowed to be used for transmissions. + * Bit 0 indicates channel 1, bit 1 indicates channel 2, etc. + * Set to 0 indicate EDMG not supported. + * @bw_config: Channel BW Configuration subfield encodes + * the allowed channel bandwidth configurations + */ +struct ieee80211_edmg { + u8 channels; + enum ieee80211_edmg_bw_config bw_config; +}; + +/** * struct ieee80211_supported_band - frequency band definition * * This structure describes a frequency band a wiphy @@ -333,6 +387,7 @@ struct ieee80211_sband_iftype_data { * @n_bitrates: Number of bitrates in @bitrates * @ht_cap: HT capabilities in this band * @vht_cap: VHT capabilities in this band + * @edmg_cap: EDMG capabilities in this band * @n_iftype_data: number of iftype data entries * @iftype_data: interface type data entries.
