2020-04-25net: hns3: optimize the filter table entries handling when resettingJian Shen1-44/+45
Currently, the PF driver removes all (including its VFs') MAC/VLAN flow director table entries when resetting, and restores them after reset completed. In fact, the hardware will clear all table entries only in IMP reset and global reset. So driver only needs to restore the table entries in these cases, and needs do nothing when PF reset, FLR or other function level reset. This patch optimizes it by removing unnecessary table entries clear and restoring handling in the reset flow, and doing the restoring after reset completed.

2020-04-25net: hns3: use mutex vport_lock instead of mutex umv_lockJian Shen1-12/+19
Currently, the driver use mutex umv_lock to protect the variable vport->share_umv_size. And there is already a mutex vport_lock being defined in the driver, which is designed to protect the resource of vport. So we can use vport_lock instead of umv_lock. Furthermore, there is a time window for protect share_umv_size between checking UMV space and doing MAC configuration in the lin function hclge_add_uc_addr_common(). It should be extended. This patch uses mutex vport_lock intead of spin lock umv_lock to protect share_umv_size, and adjusts the mutex's range.

2020-04-25net: hns3: refactor the promisc mode settingJian Shen1-15/+74
As the HNS3 driver doesn't update the MAC address directly in function hns3_set_rx_mode() now, it can't know whether the MAC table is full from __dev_uc_sync() and __dev_mc_sync(), so it's senseless to handle the overflow promisc here. This patch removes the handle of overflow promisc from function hns3_set_rx_mode(), and updates the promisc mode in the service task.

2020-04-25net: hns3: refactor the MAC address configureJian Shen1-89/+503
Currently, the HNS3 driver sync and unsync MAC address in function hns3_set_rx_mode(). For PF, it adds and deletes MAC address directly in the path of dev_set_rx_mode(). If failed, it won't retry until next calling of hns3_set_rx_mode(). On the other hand, if request add and remove a same address many times at a short interval, each request must be done one by one, can't be merged. For VF, it sends mailbox messages to PF to request adding or deleting MAC address in the path of function hns3_set_rx_mode(), no matter the address is configured success. This patch refines it by recording the MAC address in function hns3_set_rx_mode(), and updating MAC address in the service task. If failed, it will retry by the next calling of periodical service task. It also uses some state to mark the state of each MAC address in the MAC list, which can help merge configure request for a same address. With these changes, when global reset or IMP reset occurs, we can restore the MAC table with the MAC list.

2020-04-25net: hns3: refine for unicast MAC VLAN space managementJian Shen1-48/+24
Currently, firmware helps manage the unicast MAC VLAN table space for each PF. PF just needs to tell firmware its wanted space when initializing, and unnecessary to free it when un-intializing. So this patch removes the umv space free handle, and removes the forward statement of hclge_set_umv_space() by defining hclge_init_umv_space() after it.

This patch cleans up some incorrect type in assignment reported by sparse and compiler. The warning as below: - warning : restricted __le16 degrades to integer - warning : cast from restricted __le32 - warning : cast from restricted __be32 - warning : cast from restricted __be16 and "mixed operation".

2020-03-05net: hns3: fix a not link up issue when fibre port supports autonegJian Shen1-1/+3
When fibre port supports auto-negotiation, the IMP(Intelligent Management Process) processes the speed of auto-negotiation and the user's speed separately. For below case, the port will get a not link up problem. step 1: disables auto-negotiation and sets speed to A, then the driver's MAC speed will be updated to A. step 2: enables auto-negotiation and MAC gets negotiated speed B, then the driver's MAC speed will be updated to B through querying in periodical task. step 3: MAC gets new negotiated speed A. step 4: disables auto-negotiation and sets speed to B before periodical task query new MAC speed A, the driver will ignore the speed configuration. This patch fixes it by skipping speed and duplex checking when fibre port supports auto-negotiation.

2020-02-14net: hns3: fix a copying IPv6 address error in hclge_fd_get_flow_tuples()Guangbin Huang1-6/+9
The IPv6 address defined in struct in6_addr is specified as big endian, but there is no specified endian in struct hclge_fd_rule_tuples, so it will cause a problem if directly use memcpy() to copy ipv6 address between these two structures since this field in struct hclge_fd_rule_tuples is little endian. This patch fixes this problem by using be32_to_cpu() to convert endian of IPv6 address of struct in6_addr before copying.

2020-01-11net: hns3: refactor the notification scheme of PF resetHuazhong Tan1-23/+19
hclge_reset_prepare_down() is only used to inform VF that PF is going to do function reset, then using hclge_func_reset_sync_vf() in hclge_reset_prepare_wait() to query whether VF is ready before asserting PF function reset. To make the code more readable, this patch uses a new function hclge_function_reset_notify_vf() to do this job. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.
