Jakub Kicinski 3d780b926a nfp: add async reconfiguration mechanism ... Some callers of nfp_net_reconfig() are in atomic context so we used to busy wait for commands to complete. In worst case scenario that means locking up a core for up to 5 seconds when a command times out. Lets add a timer-based mechanism of asynchronously checking whether reconfiguration completed successfully for atomic callers to use. Non-atomic callers can now just sleep. The approach taken is quite simple because (1) synchronous reconfigurations always happen under RTNL (or before device is registered); (2) we can coalesce pending reconfigs. There is no need for request queues, timer which eventually takes a look at reconfiguration result to report errors is good enough.
