  To: dev

From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

Currently, when receiving and transmitting packets based on hns3 network
engine there are probably unexpected and redundant Tx interrupts if Rx
interrupt is enabled.

The root cause as below:
Tx and Rx queues with the same number share the interrupt vector in hns3
network engine, and in this case there are the residual hardware mapping
relationship configuration between queue and interrupt vector configured
in hns3 kernel ethdev driver.

We should clear the all hardware mapping relationship configrations in the
initialization. Because of the hardware constraints, we have to implement
clearing the relationship by binding all queues to the last interrupt
vector and reserving the last interrupt vector, this method results in a
decrease of the maximum queues when upper applications call the
rte_eth_dev_configure API function to enable Rx interrupt.

Fixes: 02a7b55657b2 ("net/hns3: support Rx interrupt")

The hns3 PF/VF devices on the same port share the hardware MTU
configuration. Currently, we send mailbox to inform hns3 PF kernel
ethdev driver to finish hardware MTU configuration in hns3 VF PMD
driver, there is no need to stop the port for hns3 VF device, and
the MTU value issued by hns3 VF PMD driver must be less than or
equal to PF's MTU.

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, we only support VF device is bound to vfio_pci or igb_uio and
then driven by DPDK driver when PF is driven by kernel mode hns3 ethdev
driver, VF is not supported when PF is driven by hns3 DPDK driver.

This patch adds promiscuous and allmulticast mode support for hns3 VF PMD
driver.
1) The promiscuous/allmulticast mode can be configured successfully only
   based on the trusted VF device. If based on the non trusted VF device,
   configuring promiscuous/allmulticast mode will fail. The hns3 VF device
   can be confiruged as trusted device by hns3 PF kernel ethdev driver on
   the host by "ip link set <eth num> vf <vf id> turst on" command.
2) After the promiscuous mode is configured successfully, hns3 VF PMD
   driver can receive the ingress and outgoing traffic. In the words, all
   the ingress packets, all the packets sent from the PF and other VFs on
   the same physical port.
3) Note: Because of the hardware constraints, By default vlan filter is
   enabled and couldn't be turned off based on VF device, so vlan filter
   is still effective even in promiscuous mode. If upper applications
   don't call rte_eth_dev_vlan_filter API function to set vlan based on
   VF device, hns3 VF PMD driver will can't receive the packets with vlan
   tag in promiscuoue mode.

* [dpdk-dev] [PATCH 5/5] net/hns3: fix promiscuous mode for PF
  2020-03-07  8:57 [dpdk-dev] [PATCH 0/5] misc updates and fixes for hns3 PMD driver Wei Hu (Xavier)
                   ` (3 preceding siblings ...)
  2020-03-07  8:57 ` [dpdk-dev] [PATCH 4/5] net/hns3: support promiscuous and allmulticast mode for VF Wei Hu (Xavier)
@ 2020-03-07  8:57 ` Wei Hu (Xavier)

From: Wei Hu (Xavier) @ 2020-03-07  8:57 UTC (permalink / raw)
  To: dev

From: Chengchang Tang <tangchengchang@huawei.com>

Currently, when promiscuous mode is enabled, it is just allowed to accept
all the unicast and broadcast packets in hns3 PF PMD driver. It should
also be able to receive multicast packets.

Fixes: 19a3ca4c99cf ("net/hns3: add start/stop and configure operations")
