This value records a manual recovery action an administrator has requested for this internal backplane link, such as a re-acknowledge or reset, as opposed to something UCS Manager triggered automatically. It matters on the internal Ethernet link that carries a blade's traffic from the chassis I/O Module up to a Fabric Interconnect over the backplane because it is the audit trail showing a human intervened in this link's lifecycle, which matters when reviewing why a link's history includes an unexpected reset. Seeing userRecoveryOperation set to a reset action on this backplane link right before a brief outage explains the outage as a deliberate admin action rather than an unexpected failure.
