Subject: [dpdk-stable] [PATCH] net/ice: fix wrong data path selection in secondary process
Date: Mon, 24 May 2021 17:06:08 +0800 [thread overview]
Message-ID: <20210524090608.980484-1-qi.z.zhang@intel.com> (raw)
The flag use_avx2 and use_avx512 are defined as local variables, they
will not be aware by the secondary process, then wrong data path is
selected. Fix the issue by moving them into struct ice_adapter.
Fixes: ae60d3c9b227 ("net/ice: support Rx AVX2 vector")
Fixes: 2d5f6953d56d ("net/ice: support vector AVX2 in Tx")
Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")
