Subject: [dpdk-stable] [PATCH 1/2] net/i40e: fix generic build on FreeBSD
Date: Wed, 18 Aug 2021 17:38:15 +0100	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

The common header file for vectorization is included in multiple files,
and so must use macros for the current compilation unit, rather than the
compiler-capability flag set for the whole driver. With the current,
incorrect, macro, the AVX512 or AVX2 flags may be set when compiling up
SSE code, leading to compilation errors. Changing from "CC_AVX*_SUPPORT"
to the compiler-defined "__AVX*__" macros fixes this issue.

Bugzilla ID: 788
Fixes: 0604b1f2208f ("net/i40e: fix crash in AVX512")
