X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fe28ed3f29617e6b5f3e366fd5673c4fe2c65464;p=thirdparty%2Fhostap.git

tests: Secure mesh network plink counting during reconnection

This verifies that num_plinks is decremented properly if a peer mesh STA
reconnects without closing the link explicitly.
