Subject: [PATCH] ice: avoid bonding causing auxiliary plug/unplug under RTNL
lock
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.
