Subject: [PATCH v3] net/ice: fix secondary process Rx offload path
Date: Tue, 16 Nov 2021 10:32:09 +0800
Message-ID: <20211116023209.18252-1-alvinx.zhang@intel.com> (raw)
In-Reply-To: <20211115020539.20468-1-alvinx.zhang@intel.com>

Secondary process depends on the vector offload flag to select right
Rx offload path. This patch adds a variable in share memory to store
the vector offload flag that can be directly read by secondary process.

Fixes: 808a17b3c1e6 ("net/ice: add Rx AVX512 offload path")
Cc: stable@dpdk.org

Signed-off-by: Alvin Zhang <alvinx.zhang@intel.com>

v3: Modify the patch according to comment.
