Sync some patchs from upstreaming for hns3 pmd and modifications are as follow: - dma/hisilicon: remove support for HIP09 platform - net/hns3: disable SCTP verification tag for RSS hash input - net/hns3: fix variable overflow - net/hns3: fix double free for Rx/Tx queue - net/hns3: fix read Rx timestamp handle - net/hns3: fix offload flag of IEEE 1588 In addition, the following patch synchronizes the latest version - ethdev: fix strict aliasing lead to link cannot be up Signed-off-by: Dengdui Huang <huangdengdui@huawei.com> (cherry picked from commit 60fad33c2a49d948d5816889cb40f0184f826149)

Subject: [PATCH 41/42] net/hns3: disable SCTP verification tag for RSS hash
|
|
input
|
|
|
|
[ upstream commit 47d5fa9a91989c4671ecb8c3a7e767572846570c ]
|
|
|
|
When the symmetric RSS algorithm is used, the same packet is
|
|
expected to be hashed to the same queue in the upstream and
|
|
downstream directions.
|
|
|
|
The problem is that it could map the packets in the same SCTP
|
|
connection to different NIC RX queues depending on the direction
|
|
of packets. This is because the verification Tag is used as the
|
|
RSS hash input for the SCTP packets, and the value depends on the
|
|
peer end of the SCTP connection and could not be symmetrically
|
|
used in the hardware-implemented RSS algorithm.
|
|
|
|
In addition, the ethdev framework doesn't support setting SCTP
|
|
V-tag as the RSS hash input. So disable it for all RSS hash
|
|
algorithms.
