RDMA is not supported in ice on a PF that has been added to a bonded interface. To enforce this, when an interface enters a bond, we unplug the auxiliary device that supports RDMA functionality. This unplug currently happens in the context of handling the netdev bonding event. This event is sent to the ice driver under RTNL context. This is causing a deadlock where the RDMA driver is waiting for the RTNL lock to complete the removal. Defer the unplugging/re-plugging of the auxiliary device to the service task so that it is not performed under the RTNL lock context.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
