Subject: [dpdk-dev] [PATCH v2 1/4] net/bnx2x: fix build with gcc11
Date: Tue, 11 May 2021 12:44:51 +0100	[thread overview]
Message-ID: <20210511114454.3923410-1-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20210510150319.1496105-1-ferruh.yigit@intel.com>

Reproduced with '--buildtype=debugoptimized' config,
compiler version: gcc (GCC) 12.0.0 20210509 (experimental)

Build error:
In file included from ../drivers/net/bnx2x/bnx2x_rxtx.c:8:
../drivers/net/bnx2x/bnx2x_rxtx.c: In function ‘bnx2x_upd_rx_prod_fast’:

REG_WR32 requires 'uint32_t', use union instead of cast to 'uint32_t'.
