This patch series is being submitted as a Request For Comment only. It depends on code submitted to the rdma subsystem [1]. This work is the first submission aimed to satisfy the TODO item for removing duplicated code in hfi1. At the time of submission hfi1 and qib contained alot of duplicated verbs processing code. The qib driver is having similar changes made to use rdmavt. This will result in a common code base that both drivers and future drivers such as soft-roce can use. Note that due to the ongoing submission of hfi1 improvement patches, there will likely be a number of conflicts which will still need to be resolved. We also are still faced with the issue of separate trees for this work as was discussed previously [2]. The result of that conversation was to keep the drivers in separate trees until the 4.5 merge window. We are hoping that after this merge window a single maintainer can take control of hfi1, qib, and rdmavt so that these patches can move forward and be applied. For now though we would like to get feedback on these patches with more to follow.
