Miller" , Eric Dumazet , Jakub Kicinski , Shuah Khan , linux-kselftest@vger.kernel.org Subject: [PATCH net] selftests: net: give more time for GRO aggregation Date: Thu, 25 Jan 2024 19:09:06 +0100 Message-ID: Precedence: bulk X-Mailing-List: linux-kselftest@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 X-Scanned-By: MIMEDefang 3.4.1 on 10.11.54.6 The gro.sh test-case relay on the gro_flush_timeout to ensure that all the segments belonging to any given batch are properly aggregated. The other end, the sender is a user-space program transmitting each packet with a separate write syscall. A busy host and/or stracing the sender program can make the relevant segments reach the GRO engine after the flush timeout triggers. Give the GRO flush timeout more slack, to avoid sporadic self-tests failures.
