When reusing a command description read from HW, driver should set IN_VLD bit, WR bit and NO_INTR bit. If IN_VLD bit and NO_INTR bit are not set, the command fails and driver prints error message: [ 135.261284] hns3 0000:7d:00.0: cmdq execute failed for get_mac_vlan_cmd_status,status=2. [ 135.270983] hns3 0000:7d:00.0: add mac addr failed for cmd_send, ret =-5. This patch fixes the bug.

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.
