Subject: hostapd: ucode: filter MLD loops by phy in phy_set_state/phy_status
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26a4d5080669d5196e406541d7ac6c2d4d0a5044;p=thirdparty%2Fopenwrt.git

hostapd: ucode: filter MLD loops by phy in phy_set_state/phy_status

The per-wiphy radio-mask loops iterated all MLDs without checking the phy,
so a stop/start or status query for one wiphy touched MLDs on another wiphy
with the same radio index (clearing present bits, tearing links down, or
reporting a foreign MLD). Skip MLDs that do not belong to the phy, matching
mld_update_phy().
