2019-08-09net: hns3: fix interrupt clearing error for VFHuazhong Tan2-9/+21
Currently, VF driver has two kinds of interrupts, reset & CMDQ RX. For revision 0x21, according to the UM, each interrupt should be cleared by write 0 to the corresponding bit, but the implementation writes 0 to the whole register in fact, it will clear other interrupt at the same time, then the VF will loss the interrupt. But for revision 0x20, this interrupt clear register is a read & write register, for compatible, we just keep the old implementation for 0x20. This patch fixes it, also, adds a new register for reading the interrupt status according to hardware user manual.

2019-08-01net: hns3: clear reset interrupt status in hclge_irq_handle()Huazhong Tan2-10/+22
Currently, the reset interrupt is cleared in the reset task, which is too late. Since, when the hardware finish the previous reset, it can begin to do a new global/IMP reset, if this new coming reset type is same as the previous one, the driver will clear them together, then driver can not get that there is another reset, but the hardware still wait for the driver to deal with the second one. So this patch clears PF's reset interrupt status in the hclge_irq_handle(), the hardware waits for handshaking from driver before doing reset, so the driver and hardware deal with reset one by one. BTW, when VF doing global/IMP reset, it reads PF's reset interrupt register to get that whether PF driver's re-initialization is done, since VF's re-initialization should be done after PF's. So we add a new command and a register bit to do that. When VF receive reset interrupt, it sets up this bit, and PF finishes re-initialization send command to clear this bit, then VF do re-initialization.

2019-08-01net: hns3: fix some reset handshake issueHuazhong Tan3-9/+33
Currently, the driver sets handshake status to tell the hardware that the driver have downed the netdev and it can continue with reset process. The driver will clear the handshake status when re-initializing the CMDQ, and does not recover this status when reset fail, which may cause the hardware to wait for the handshake status to be set and not being able to continue with reset process. So this patch delays clearing handshake status just before UP, and recovers this status when reset fail. BTW, this patch adds a new function hclge(vf)_reset_handshake() to deal with the reset handshake issue, and renames HCLGE(VF)_NIC_CMQ_ENABLE to HCLGE(VF)_NIC_SW_RST_RDY which represents this register bit more accurately.
