net: hns3: fix data endian problem of some functions of debugfs
Browse files Browse the repository at this point in the history 
The member data in struct hclge_desc is type of __le32, it needs endian
conversion before using it, and some functions of debugfs didn't do that,
so this patch fixes it.

Fixes: c0ebebb ("net: hns3: Add "dcb register" status information query function")
