Subject: [net-next V2 08/14] net/mlx5: DR, In rehash write the line in the entry immediately
Date: Thu, 27 Oct 2022 15:56:37 +0100 [thread overview]
Message-ID: <20221027145643.6618-9-saeed@kernel.org> (raw)
In-Reply-To: <20221027145643.6618-1-saeed@kernel.org>
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
Don't wait for the whole table to be ready - write each row immediately.
This way we save allocations of the ste_send_info structure and improve
performance.
