net: hns3: add support for dump ncl config by debugfs
This patch allow users to dump content of NCL_CONFIG by using debugfs
command.
Command format:
echo dump ncl_config <offset> <length> > cmd
It will print as follows:
hns3 0000:7d:00.0: offset | data
hns3 0000:7d:00.0: 0x0000 | 0x00000020
hns3 0000:7d:00.0: 0x0004 | 0x00000400
hns3 0000:7d:00.0: 0x0008 | 0x08020401
