RDMA/hns: Bugfix for set hem of SCC
The method of set hem for scc context is different from other contexts. It should notify the hardware with the detailed idx in bt0 for scc, while for other contexts, it only need to notify the bt step and the hardware will calculate the idx. Here fixes the following error when unloading the hip08 driver: [ 123.570768] {1}[Hardware Error]: Hardware error from APEI Generic Hardware Error Source: 0 [ 123.579023] {1}[Hardware Error]: event severity: recoverable [ 123.584670] {1}[Hardware Error]: Error 0, type: recoverable [ 123.590317] {1}[Hardware Error]: section_type: PCIe error [ 123.595877] {1}[Hardware Error]: version: 4.0 [ 123.600395] {1}[Hardware Error]: command: 0x0006, status: 0x0010 [ 123.606562] {1}[Hardware Error]: device_id: 0000:7d:00.0 [ 123.612034] {1}[Hardware Error]: slot: 0 [ 123.616120] {1}[Hardware Error]: secondary_bus: 0x00 [ 123.621245] {1}[Hardware Error]: vendor_id: 0x19e5, device_id: 0xa222 [ 123.627847] {1}[Hardware Error]: class_code: 000002 [ 123.632977] hns3 0000:7d:00.0: aer_status: 0x00000000, aer_mask: 0x00000000 [ 123.639928] hns3 0000:7d:00.0: aer_layer=Transaction Layer, aer_agent=Receiver ID [ 123.647400] hns3 0000:7d:00.0: aer_uncor_severity: 0x00000000 [ 123.653136] hns3 0000:7d:00.0: PCI error detected, state(=1)!!
