2020-05-14net: hns3: remove unnecessary frag list checking in hns3_nic_net_xmit()Huazhong Tan1-4/+1

The 802.3 specification does not specify the behavior of auto-negotiation off with 1000M in PHY. Therefore, some PHY compatibility issues occur.

2020-04-25net: hns3: optimize the filter table entries handling when resettingJian Shen8-105/+94
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 Shen2-13/+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 Shen8-46/+122
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 Shen6-218/+860
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.

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.

2020-03-21net: hns3: refactor mailbox response scheme between PF and VFHuazhong Tan3-155/+113
Currently, PF responds to VF depending on what mailbox it is handling, it is a bit inflexible. The correct way is, PF should check the mbx_need_resp field to decide whether gives response to VF.

2020-03-21net: hns3: refactor the mailbox message between PF and VFYufeng Mo5-234/+291
For making the code more readable, this adds several new structure to replace the msg field in structure hclge_mbx_vf_to_pf_cmd and hclge_mbx_pf_to_vf_cmd. Also uses macro to instead of some magic number. Signed-off-by: Yufeng Mo <moyufeng@huawei.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2020-03-21net: hns3: add a conversion for mailbox's response codeJian Shen2-2/+21
Currently, when mailbox handling fails, the PF driver just responds 1 to the VF driver. It is not sufficient for the VF driver to find out why its mailbox fails. So the error should be responded to VF, but the error is type int and the response field in struct hclge_mbx_pf_to_vf_cmd is type u16, a conversion is needed.

2020-03-12net: hns3: clear port base VLAN when unload PFJian Shen1-0/+23
Currently, PF missed to clear the port base VLAN for VF when unload. In this case, the VLAN id will remain in the VLAN table. This patch fixes it.

2020-03-12net: hns3: fix RMW issue for VLAN filter switchJian Shen1-4/+15
According to the user manual, the ingress and egress VLAN filter are configured at the same time. Currently, hclge_init_vlan_config() and hclge_set_vlan_spoofchk() will both change the VLAN filter switch. So it's necessary to read the old configuration before modifying it.

2020-03-12net: hns3: fix VF VLAN table entries inconsistent issueJian Shen4-0/+6
Currently, if VF is loaded on the host side, the host doesn't clear the VF's VLAN table entries when VF removing. In this case, when doing reset and disabling sriov at the same time the VLAN device over VF will be removed, but the VLAN table entries in hardware are remained. This patch fixes it by asking PF to clear the VLAN table entries for VF when VF is removing. It also clears the VLAN table full bit after VF VLAN table entries being cleared.

The HNS3 driver supports to configure TC numbers and TC to priority map via "tc" tool. But when delete the rule, will fail, because the HNS3 driver needs at least one TC, but the "tc" tool sets TC number to zero when delete. This patch makes sure that the TC number is at least one.
