[PATCH 12/54] fcoe: add a separate scsi transport template for NPIV vports

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Chris Leech <christopher.leech@xxxxxxxxx>

Right now it's exactly the same as the physical port template,
and there is no way to create a port on anything other than the
netdev.  When the vport_create entry point gets hooked up it will
create lports on top of vport devices, which will use this.

Rename scsi_transport_fcoe_sw to fcoe_transport_template to be more
clear with naming now that there are two templates.
