Client close is overloaded to handle both un-registration and netdev down event. On netdev down, i40iw client close is called which unregisters the RDMA dev and this is too destructive since the netdev is still registered. Do not call client close/open on netdev down/up events. Instead disable the PE TCP_ENA flag during a netdev down event. This blocks all TCP traffic to the RDMA Protocol Engine. On netdev up, re-enable the flag.

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.
