I ended up only having the time to complete one of the additional drivers. During Dave Miller's pull request this go around, there were a series of 9 patches to the QLogic qed net driver that add basic support for a paired RoCE driver. That support is currently not functional because it is missing the matching RoCE driver in the RDMA subsystem. I managed to finish that review. However, because it goes against part of Dave's net pull, and a part that was accepted a day or two after the merge window opened, to apply cleanly it has to be applied to either the tip of Dave's net branch, or as I did in this case, I just applied it to your master after you had taken Dave's pull request." * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: qedr: Add events support and register IB device qedr: Add GSI support qedr: Add LL2 RoCE interface qedr: Add support for data path qedr: Add support for memory registeration verbs qedr: Add support for QP verbs qedr: Add support for PD,PKEY and CQ verbs qedr: Add support for user context verbs qedr: Add support for RoCE HW init qedr: Add RoCE driver framework
