[dpdk-dev] [PATCH v2 10/20] net/dpaa2: add support for raw pattern in dpdmux

[Hemant Agrawal <hemant.agrawal@nxp.com>]

From: Akhil Goyal <akhil.goyal@nxp.com>

Added support for flow raw pattern and check that the call
for dpdmux_set_custom_key() which should be called
only once for a particular DPDMUX as all previous rules
will be erased with this call.
Hence calling it for the first time only.
