      ( ) The acceptance criteria defined below are met.

      Given a system running NetworkManager,
      When a sysadmin (via nmcli or Nmstate) creates and activates an IPsec transport profile that specifies libreswan.esp=aes_gcm256,

      Then the VPN connection reaches NM_ACTIVE_CONNECTION_STATE_ACTIVATED and the generated ipsec.conf contains only a single esp= line with no phase2alg= entries, so ipsec addconn no longer logs “duplicate key 'phase2alg'” during activation.
      Also, check the other options that might be impacted by this bug.

      ( ) Integration test case is available upstream.

      ( ) Code is reviewed and merged upstream.

      ( ) Preliminary testing is done.
