Subject: tests: Make GAS/ANQP test cases more robust
X-Git-Tag: hostap_2_11~2238
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f5ce9111c5993945ebd428e3736a9e66b5f08e49;p=thirdparty%2Fhostap.git

tests: Make GAS/ANQP test cases more robust

Flush the scan cache for all test cases that used get_bss() to check for
particular ANQP information. This was already done for one such case
based on commit dd900637b2d0 ("tests: Make gas_anqp_extra_elements more
robust"), but other test cases need this as well.

This was showing with frequent errors in test cases sequences like this
one:
dfs_radar_no_ht gas_fragment_with_comeback_delay gas_unknown_adv_proto gas_anqp_venue_url
