Subject: [PATCH 015/189] net/hns3: fix register length when dumping registers
|
|
|
|
Currently, the reg length return by HNS3 is the total length of all the
|
|
registers. But for upper layer user, the total register length is the
|
|
length multiplied by width. This can lead to a waste of memory and print
|
|
some invalid information.
|
|
|
|
This patch corrects the length and width of the register.
|
|
|
|
Fixes: 936eda25e8da ("net/hns3: support dump register")
