Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe:
"A more active cycle than most of the recent past, with a few large,
long discussed works this time.
The RNBD block driver has been posted for nearly two years now, and
flowing through RDMA due to it also introducing a new ULP.
The removal of FMR has been a recurring discussion theme for a long
time.
And the usual smattering of features and bug fixes.
Summary:
- Various small driver bugs fixes in rxe, mlx5, hfi1, and efa
- Continuing driver cleanups in bnxt_re, hns
- Big cleanup of mlx5 QP creation flows
- More consistent use of src port and flow label when LAG is used and
a mlx5 implementation
- Additional set of cleanups for IB CM
- 'RNBD' network block driver and target. This is a network block
RDMA device specific to ionos's cloud environment. It brings strong
multipath and resiliency capabilities.
- Accelerated IPoIB for HFI1
- QP/WQ/SRQ ioctl migration for uverbs, and support for multiple
async fds
- Support for exchanging the new IBTA defiend ECE data during RDMA CM
exchanges
- Removal of the very old and insecure FMR interface from all ULPs
and drivers. FRWR should be preferred for at least a decade now"
