Subject: [dpdk-dev] [PATCH v4 5/5] net/mlx5: update modify field action
Date: Tue, 12 Oct 2021 13:49:19 +0300 [thread overview]
Message-ID: <20211012104919.13145-6-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20211012104919.13145-1-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
