Please pull RDMA subsystem changes
Hi Linus,
This is the next batch of for-rc patches from RDMA. It includes the fix for the ipoib regression I mentioned last time, and the result of a fairly major debugging effort to get iser working reliably on cxgb4 hardware - it turns out the cxgb4 driver was not handling QP error flushing properly causing iser to fail.
I was on the fence for the LAG counters bug fix at rc6. In the end this appears to be a user space API issue, as data exposed to user space is not correct under certain device configurations. I also expect this patch will go to -stable.
The following changes since commit 9d98e19ba08f6aa33a4a1414f3dfe8440e67530c:
IB/ipoib: Restore MM behavior in case of tx_ring allocation failure (2017-12-13 10:31:57 -0700)

IB/mlx5: Fix mlx5_ib_alloc_mr error flow (2017-12-27 15:24:41 -0700)
----------------------------------------------------------------
Third pull request for 4.15-rc
- cxgb4 fix for an iser testing failure as debugged by Steve and Sagi. The problem was a driver bug in the handling of shutting down a QP.
- Various vmw_pvrdma fixes for bogus WARN_ON, missed resource free on error unwind and a use after free bug
- Improper congestion counter values on mlx5 when link aggregation is enabled
- ipoib lockdep regression introduced in this merge window
- hfi1 regression supporting the device in a VM introduced in a recent patch
- Typo that breaks future uAPI compatibility in the verbs core
- More SELinux related oops fixing
- Fix an oops during error unwind in mlx5
