2019-01-02net-next/hinic:add shutdown callbackXue Chaojing1-0/+6
If there is no shutdown callback, our board will report pcie UNF errors after restarting. This patch add shutdown callback for hinic. Signed-off-by: Xue Chaojing <xuechaojing@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-11-20net-next/hinic:fix a bug in set mac addressXue Chaojing1-3/+4
In add_mac_addr(), if the MAC address is a muliticast address, it will not be set, which causes the network card fail to receive the multicast packet. This patch fixes this bug. Signed-off-by: Xue Chaojing <xuechaojing@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-11-20net-next/hinic:add rx checksum offload for HiNICXue Chaojing1-1/+6
In order to improve performance, this patch adds rx checksum offload for the HiNIC driver. Performance test(Iperf) shows more than 80% improvement in TCP streams. Signed-off-by: Xue Chaojing <xuechaojing@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-10-19net-next/hinic: add checksum offload and TSO supportZhao Chen1-1/+22
This patch adds checksum offload and TSO support for the HiNIC driver. Perfomance test (Iperf) shows more than 100% improvement in TCP streams. Signed-off-by: Zhao Chen <zhaochen6@huawei.com> Signed-off-by: Xue Chaojing <xuechaojing@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-28hinic: remove ndo_poll_controllerEric Dumazet1-20/+0
As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. hinic uses NAPI for TX completions, so we better let core networking stack call the napi->poll() to avoid the capture. Note that hinic_netpoll() was incorrectly scheduling NAPI on both RX and TX queues.

2018-07-25hinic: Link the logical network device to the pci device in sysfsdann frazier1-0/+1
Otherwise interfaces get exposed under /sys/devices/virtual, which doesn't give udev the context it needs for PCI-based predictable interface names. Signed-off-by: dann frazier <dann.frazier@canonical.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-05-08net-next/hinic: add pci device ids for 25ge and 100ge cardZhao Chen1-2/+6
This patch adds PCI device IDs to support 25GE and 100GE card: 1. Add device id 0x0201 for HINIC 100GE dual port card. 2. Add device id 0x0200 for HINIC 25GE dual port card. 3. Macro of device id 0x1822 is modified for HINIC 25GE quad port card. Signed-off-by: Zhao Chen <zhaochen6@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
