 Low latency busy poll timeout for socket reads. (needs CONFIG_NET_LL_RX_POLL)

-low_latency_poll
+busy_poll
 ----------------
 Low latency busy poll timeout for poll and select. (needs CONFIG_NET_LL_RX_POLL)
 Approximate time in us to busy loop waiting for events.
 Recommended value depends on the number of sockets you poll on.
 For several sockets 50, for several hundreds 100.
 For more than that you probably want to use epoll.
-Note that only sockets with SO_LL set will be busy polled, so you want to either
-selectively set SO_LL on those sockets or set sysctl.net.low_latency_read globally.
