    [IPoIB] add path record information in debugfs · 1732b0ef
    Roland Dreier authored
    Add ibX_path files to debugfs that contain information about the IPoIB
    path cache.  IPoIB ARP only gives GIDs, which the IPoIB driver must
    resolve to real IB paths through the ib_sa module.  For debugging,
    when the ARP table looks OK but traffic isn't flowing, it's useful to
    be able to see if the resolution from GID to path worked.
    
    Also clean up the formatting of the existing _mcg debugfs files.
