Subject: net/dpaa2: use hash FLCTYPE only for LX2
X-Git-Tag: spdx-start~85
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ffb3389ceff0f70a9ed4a34100d74cbe81042a60;p=dpdk.git

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.
