Subject: libhns: Add RoH device IDs
|
||||
|
||||
Add RoH device IDs.
|
||||
0xA227 is a 100Gb/s RoH device, and it was mistakenly added before.
|
||||
0xA22C is a 200Gb/s RoH device.
|
||||
0xA22D is a 400Gb/s RoH device.

Subject: libhns: Add the parsing of mac type in RoH mode
|
||||
|
||||
After parsing the mac type as RoH mode, the user driver
|
||||
needs to set the dmac field of ud wqe to 0xFF, the hardware
|
||||
will recognize this field, and increase the recognition of
|
||||
the IP field in RoH mode, which is used for the CM link
|
||||
building function in user mode.
