Subject: [PATCH v2 03/26] net/ntnic: replace pragma pack with DPDK defined macros
Date: Mon,  5 May 2025 09:12:43 +0200	[thread overview]
Message-ID: <20250505071309.586015-4-okl-plv@napatech.com> (raw)
In-Reply-To: <20250505071309.586015-1-okl-plv@napatech.com>

The macros __rte_packed_begin and __rte_packed_end are used instead
of #pragma pack(1) when structure or union memory should be minimized.
