I would suggest that when the actual RoCE driver is posted, we merge these 2 prerequisite patches + the driver through my tree, to avoid the hassle of a dependency between my tree and Dave's net-next tree. [PP] There are minor differences in be2net driver in your tree and net-next tree. So if we are fine with the interface between RoCE driver and NIC driver which is already available in this patch, then you can just merge RoCE driver patch from your tree to net-next tree. There will be separate patch against net-next tree for NIC driver which will be almost similar to this one. (Assuming these patches are OK with Dave and everyone else... they look pretty reasonable to me after a quick read) When do you expect to post the actual RoCE driver? If that's going to be a while, another possibility is to just merge these patches through net-next for 3.4, although I'm not sure about how Dave feels about merging all this stuff without seeing what will actually use it. [PP] I was just waiting for comments on this RFC/PATCH to submit separate patch for RoCE driver. But surely if RoCE driver patch helps review, I can send it right away. I'll prepare the patch for Roland's tree and send in few hours.
