Cover letter [PATCH rdma-next v1 0/2] PCI write end padding capability
Changelog v0->v1:
* Rename *_SCATTER_END_PADDING flags to be *_PCI_WRITE_END_PADDING
---------------------------------------
There are PCIe root complex that are able to optimize their performance when incoming data is multiple full cache lines.
Expose the device capability to pad the ending of incoming packets to full cache line such that the last upstream write generated by the incoming packet will be a full cache line.
The patches are available in the git repository at:
git.kernel.org/pub/scm/linux/kernel/git/leon/linux-rdma.git tags/rdma-next-2017-10-29
Thanks
