This patch fixes the issue specific to AP. AP is started with WEP security and external station is connected to it. Data path works in this case. Now if AP is restarted with WPA/WPA2 security, station is able to connect but ping fails. Driver skips the deletion of WEP keys if interface type is AP. Removing that redundant check resolves the issue.
