Subject: Fetch the driver EML/MLD capabilities for wpa_supplicant use
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4cc501fe68121cecb573cdb1c17b7627faac04fd;p=thirdparty%2Fhostap.git

Fetch the driver EML/MLD capabilities for wpa_supplicant use

Add a new helper function wpa_drv_get_mld_capa() to fetch MLD
capabilities based on interface type and store eml_capa and mld_capa in
wpa_supplicant and use eml_capa to decide STA EMLSR support.
