Subject: scan_est_throughput: Use ie_len instead of res->ie_len
X-Git-Tag: hostap_2_10~1885
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fee28410de6b5b5a609c656c09a434ddc48e8b91;p=thirdparty%2Fhostap.git

scan_est_throughput: Use ie_len instead of res->ie_len

Local variable should be used. This fixes an issue where IEs are
available only from a Beacon frame.

Fixes: ad06ac0b0 ("Move throughput estimation into a helper function")
