Subject: [PATCH v2] common/sfc: replace out of bounds condition with static_assert
Date: Fri, 19 Jan 2024 14:13:32 -0800 [thread overview]
Message-ID: <20240119221401.68182-1-stephen@networkplumber.org> (raw)
In-Reply-To: <20240118201843.189978-1-stephen@networkplumber.org>
The sfc base code had its own definition of static assertions
using the out of bound array access hack. Replace it with a
static_assert like rte_common.h.
Fixes: f67e4719147d ("net/sfc/base: fix coding style")
Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
Acked-by: Morten Brørup <mb@smartsharesystems.com>
