wifi: brcmsmac: Remove const from tbl_ptr parameter in wlc_lcnphy_common_read_table()

2025-07-18T12:11:18Z

A new warning in clang [1] complains that diq_start in wlc_lcnphy_tx_iqlo_cal() is passed uninitialized as a const pointer to wlc_lcnphy_common_read_table(): drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_lcn.c:2728:13: error: variable 'diq_start' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 2728 | &diq_start, 1, 16, 69); | ^~~~~~~~~ The table pointer passed to wlc_lcnphy_common_read_table() should not be considered constant, as wlc_phy_read_table() is ultimately going to update it. Remove the const qualifier from the tbl_ptr to clear up the warning.

wifi: cfg80211/mac80211: Add support to get radio index

2025-06-24T13:19:27Z

Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.
