This series focuses on RDMA in general with emphasis on required
changes toward adding iWARP support. The vast majority of the changes
introduced are in qed/qede, with a couple of small changes to qedr
[mentioned below].

Btw, can you explain us how you are going to expose RoCE vs iWarp?
Is it going to be a per-port setting?  Are you going to use different ib_device
structures or do you plan to differenciate at another level?

Initial submission will be based on iWARP or RoCE being part of the device configuration ( using EFI-Hii), 
Later on we're considering adding devlink support for changing the device configuration.
This is not a port setting, pci devices sharing the same physical port can have different RDMA protocols.
