Subject: [PATCH 017/189] net/hns3: fix dump register out of range
|
|
|
|
Currently, when dump the queue interrupt registers, the number of
|
|
registers that should be dumped is calculated from num_msi. But the
|
|
value of num_msi includes the number of misc interrupts. So, for some
|
|
hardware version, like kupeng930, it will lead to an illegal access.
|
|
|
|
This patch replace num_msi with intr_tqps_num which indicate the
|
|
number of interrupts used by the tqps.
|
|
