There's a couple of bugs in the support of max_rd_atomic and max_dest_rd_atomic. In the modify_qp, if the requested max_rd_atomic, which is the ORRQ size, is greater than what the chip can support, then we have to cap the request to chip max as we can't have the HW overflow the ORRQ. Capping the max_rd_atomic support internally is okay to do as the remaining read/atomic WRs will still be sitting in the SQ. However, for the max_dest_rd_atomic, the driver has to error out as this dictates the IRRQ size and we can't control what the remote side sends.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
