[dpdk-dev] [PATCH v1 4/5] net/hinic: add tcam filter switch for FDIR

[Xiaoyun wang]

When the filter rule needs to use the TCAM method, PMD driver
enables the TCAM filter switch, otherwise disables it, which
can improve the performance of microcode in FDIR scenarios that
not use TCAM method.

Fixes: 1fe89aa37f36 ("net/hinic: add flow director filter")
