Subject: [dpdk-dev] [PATCH v6 5/5] net/mlx5: update modify field action
Date: Wed, 13 Oct 2021 21:45:16 +0300 [thread overview]
Message-ID: <20211013184516.25338-6-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20211013184516.25338-1-viacheslavo@nvidia.com>
Update immediate value/pointer source operand support
for modify field RTE Flow action:
- source operand data can be presented by byte buffer
(instead of former uint64_t) or by pointer
- no host byte ordering is assumed anymore for immediate
data buffer (not uint64_t anymore)
- no immediate value offset is expected (the source
subfield is located at the same offset as in destination)
