From ffb3389ceff0f70a9ed4a34100d74cbe81042a60 Mon Sep 17 00:00:00 2001 From: Nipun Gupta Date: Mon, 15 Jan 2018 17:08:05 +0530 Subject: [PATCH] net/dpaa2: use hash FLCTYPE only for LX2 Enabling hash results in FD requires setting DPNI_FLCTYPE_HASH in dpni_set_offload API. Setting this FLCTYPE for DPNI sets the FD[SC] to 0 for LS2 in the hardware thus disabling data/annotation stashing. For LX2 this is fixed in hardware and thus hash result and parse results can be received in FD using this option.
