Subject: AP: MLO: Add helper to iterate all links of an AP MLD
X-Git-Tag: hostap_2_11~760
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ecb22ba12eb39bf5169851fff37c88b8d2a39726;p=thirdparty%2Fhostap.git

AP: MLO: Add helper to iterate all links of an AP MLD

Add a simple for_each_mld_link helper that sets first variable to the
hapd data for every link. It takes the interfaces and MLD ID as
arguments and two extra integers as scratch variables (for the interface
and bss offsets).
