Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"Small cycle, with some typical driver updates:
- General code tidying in siw, hfi1, idrdma, usnic, hns rtrs and
bnxt_re
- Many small siw cleanups without an overeaching theme
- Debugfs stats for hns
- Fix a TX queue timeout in IPoIB and missed locking of the mcast
list
- Support more features of P7 devices in bnxt_re including a new work
submission protocol
- CQ interrupts for MANA
- netlink stats for erdma
- EFA multipath PCI support
- Fix Incorrect MR invalidation in iser"
