Subject: [PATCH] net/iavf: fix old GCC compilation warnings
Date: Fri, 9 Jun 2023 13:41:56 +0800 [thread overview]
Message-ID: <20230609054156.605581-1-zhichaox.zeng@intel.com> (raw)
The code uses the Wimplicit-fallthrough compile option to ignore
falls through warnings in switch case, but this option was introduced
by GCC 7 and old GCC do not recognize the option.
Add judgment to avoid warnings about unrecognized options in old GCC.
Fixes: 95a1b0b23140 ("net/iavf: support Rx timestamp offload on SSE")
Fixes: 4f58266da4d3 ("net/iavf: support Rx timestamp offload on AVX2")
Fixes: d65eadb9e178 ("net/iavf: support Rx timestamp offload on AVX512")
