From cfa88893709fbf27b62c6b0cf99c72265b9a21ca Mon Sep 17 00:00:00 2001 From: Luciano Coelho Date: Tue, 19 Nov 2013 15:38:55 +0200 Subject: iwlwifi: mvm: set seqno also when no keys are set In an open BSS, after suspend/resume, we don't set the last seqno because the iwl_mvm_setup_connection_keep() returns too early. This happens because the check to see if we have any keys was returning immediately, without setting seqno and seqno_valid. Fix this.

This is because we return an integer and don't use any casting when calculating the last seqno from the one we received. Fix this by using a cast to u16 when doing the calculation, so we return 0xfff0, as we should.
