net: hns3: fix reset timeout under full functions and queues The cmdq reset command times out when all VFs are enabled and the queue is full. The hardware processing time exceeds the timeout set by the driver. In order to avoid the above extreme situations, the driver extends the reset timeout to 1 second.

net: hns3: support wake on lan configuration and query The HNS3 driver supports Wake-on-LAN, which can wake up the server from power off state to power on state by magic packet or magic security packet. ChangeLog: v1->v2: Deleted the debugfs function that overlaps with the ethtool function from suggestion of Andrew Lunn. v2->v3: Return the wol configuration stored in driver, suggested by Alexander H Duyck. v3->v4: Add a helper to go from netdev to the local struct, suggested by Simon Horman and Jakub Kicinski.

net: hns3: add getting capabilities of gro offload and fd from firmware As some new devices may not support GRO offload and flow table director, to support these devices, driver needs to querying capabilities of GRO offload and flow table director from firmware. Whether the driver supports these two features depends on capabilities. For old device of version HNAE3_DEVICE_VERSION_V2, driver sets their capabilities of these two features to fixed value. Setting default features of netdev and debugfs also need to identify whether support these two features. Signed-off-by: Guangbin Huang <huangguangbin2@huawei.com> Signed-off-by: David S.

net: hns3: create new common cmd code for PF and VF modules Currently PF and VF use two sets of command code for modules to interact with firmware. These codes values are same espect the macro names. It is redundent to keep two sets of command code for same functions between PF and VF. So this patch firstly creates a unified command code for PF and VF module. We keep the macro name same with the PF command code name to avoid too many meaningless modifications. Secondly the new common command codes are used to replace the old ones in VF and deletes the old ones. Signed-off-by: Jie Wang <wangjie125@huawei.com> Signed-off-by: David S.

net: hns3: refactor hclge_comm_send function in PF/VF drivers Currently, there are two different sets of special command codes in PF and VF cmdq modules, this is because VF driver only uses small part of all the command codes. In other words, these not used command codes in VF are also sepcial command codes theoretically. So this patch unifes the special command codes and deletes the bool param is_pf of hclge_comm_send. All the related functions are refactored according to the new hclge_comm_send function prototype. Signed-off-by: Jie Wang <wangjie125@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
