It was brought up in few occasions that the ipath driver can be
changed such that it becomes a software IBoE driver (e.g use packet
socket with the IBoE ether type for the IB L2 emulation).
If it doesn't have to serve for the qlogic HCA anymore, this
transformation might be even eaiser.
I wonder if its better to remove it now and maybe return it later with
the new facelift or leave it till the change is done.

Or.

I don't understand what you are suggesting.
The kernel module name ib_ipath and/or directory name
drivers/infiniband/hw/ipath could be reused for some
other purpose certainly.

In a 2nd thought, its better that you go and remove the hw/ipath directory, I assume the qib code could be made to serve software iboe in the same manner ipath can, just make sure to keep the IB L2 handling in separate files from the L3/L4 ones...
