---help---
If you have a network (Ethernet) card belonging to this class, say Y
and read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about Hisilicon devices. If you say Y, you will be asked
for your specific card in the following questions.
if NET_VENDOR_HISILICON

This selects the hix5hd2 mac family network device.
