RDMA/qedr: Add EDPM max size to alloc ucontext response
[ Upstream commit eb7f84e379daad69b4c92538baeaf93bbf493c14 ]
User space should receive the maximum edpm size from kernel driver,
similar to other edpm/ldpm related limits. Add an additional parameter to
the alloc_ucontext_resp structure for the edpm maximum size.
In addition, pass an indication from user-space to kernel
(and not just kernel to user) that the DPM sizes are supported.
This is for supporting backward-forward compatibility between driver and
lib for everything related to DPM transaction and limit sizes.
This should have been part of commit mentioned in Fixes tag.
