hw/rdma: Remove deprecated pvrdma device and rdmacm-mux helper
The whole RDMA subsystem was deprecated in commit e9a54265f5 ("hw/rdma: Deprecate the pvrdma device and the rdma subsystem") released in v8.2. Remove: - PVRDMA device - generated vmw_pvrdma/ directory from linux-headers - rdmacm-mux tool from contrib/ Cc: Yuval Shaia <yuval.shaia.ml@gmail.com> Cc: Marcel Apfelbaum <marcel.apfelbaum@gmail.com> Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Thomas Huth <thuth@redhat.com> Reviewed-by: Michael S.
