bool "Brocade devices"
default y
depends on PCI
---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 Brocade cards. If you say Y, you will be asked for
your specific card in the following questions.

---help---
This driver supports Brocade 1010/1020 10Gb CEE capable Ethernet
cards.
To compile this driver as a module, choose M here: the module
will be called bna.
