Currently the RoCE GID management uses the ib_wq to do add and delete new GIDs according to the netdev events. The ib_wq isn't an ordered workqueue and thus two work elements can be executed concurrently which will result in unexpected behavior and inconsistency of the GIDs cache content. Example: ifconfig eth1 11.11.11.11/16 up This command will invoke the following netdev events in the following order: 1. NETDEV_UP 2. NETDEV_DOWN 3. NETDEV_UP If (2) and (3) will be executed concurrently or in reverse order, instead of having a new GID with 11.11.11.11 IP, we will end up without any new GIDs.

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.
