    Subject[PATCH 5.14 112/125] octeontx2-af: Check whether ipolicers exists
    Date
    From: Subbaraya Sundeep <sbhatta@marvell.com>

    [ Upstream commit cc45b96e2de7ada26520f101dada0abafa4ba997 ]

    While displaying ingress policers information in
    debugfs check whether ingress policers exist in
    the hardware or not because some platforms(CN9XXX)
    do not have this feature.

    Fixes: e7d8971763f3 ("octeontx2-af: cn10k: Debugfs support for bandwidth")
