From 7f86260b5f44d93ab20d3e9afda0e3f48d005ffe Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Wed, 14 Mar 2018 16:01:50 -0600 Subject: RDMA/cxgb4: Use structs to describe the uABI instead of opencoding Open coding a loose value is not acceptable for describing the uABI in RDMA. Provide the missing struct.
