They appear to be in full compliance with the GPL:

http://www.brocade.com/services-support/drivers-downloads/oscd/FabricOS510.page

Note that there's nothing that prohibits a company from shipping a product
that has an open Linux kernel, and the "tens of thousands of lines of
closed source code" is all in userspace.

So unless you have actual proof that the Brocade switches have *kernel* code
that hasn't been offered to the users, they're not (as far as I can tell)
doing anything illegal.
