Subject: RE: [PATCH 4/5] bfa: Brocade BFA FC SCSI driver submission

Thanks James,

I agree with you. bfa driver does support all Brocade PCIe FC adapters
(we don't have PCI HBA). I will fix this in next submission.

You don't actually need this file: your Kconfig addition to scsi/Kconfig
does this.

You need also

	select SCSI_FC_ATTRS

will be called bfa

The help isn't really very helpful.  What usually goes here is something
like

This bfa driver supports all Brocade PCI and PCIe fibre channel adapters

(and if that's not true, give a list of the supported ones or the family
name).
