└─>Self test for hardware accelerated raid6 recovery
In linux kernel since version 2.6.32 (release Date: 2009-12-02)  
This is a one-shot self test that permutes through the
recovery of all the possible two disk failure scenarios for a
N-disk array. Recovery is performed with the asynchronous
raid6 recovery routines, and will optionally use an offload
engine if one is available.

If unsure, say N.
