.ndo_set_rx_mode gets called in process context, but while holding the addr_list spinlock. Which means we currently can't sleep while re-programming the HW, and need to poll for IO completion. That's bad, in particular since receiving the cmd response can fail silently and we're then polling until the timeout hits. As a first step towards eliminating the IO completion polling, run the RX modeset from a work element and only take the addr_list lock while updating the RX mode address cache. Signed-off-by:
