Your machine seems to have a different PCI SSID (17aa:3852) from the
entry above, so it's not appropriate to put here.

Instead, put one before the entry of 17aa:3852 below, with a brief
comment that it's for avoiding the confliction with the PCI SSID
17aa:3852.

... the conflicting entry is found here above.
