This read-write object turns LACP priority preemption on or off for link aggregation, defaulting to disable(2). When enabled, a higher-priority port that comes back online can preempt and take over from a currently active lower-priority member port, letting admins ensure preferred links are always used when available. Setting hwAggPreempt to enable(1) would let a preferred high-priority uplink automatically reclaim its selected role in the LAG after recovering from a failure, displacing whatever lower-priority port had taken over.
