Merge "net: finish renaming lls to busy poll"

Eliezer Tamir says:

====================
Here are three patches that complete the rename of lls to busy-poll

1. rename include/net/ll_poll.h to include/net/busy_poll.h
2. Rename ndo_ll_poll to ndo_busy_poll.
   Rename sk_mark_ll to sk_mark_napi_id.
   Rename skb_mark_ll to skb_mark_napi_id.
   Correct all useres of these functions.
   Update comments and defines  in include/net/busy_poll.h
3. Rename LL_SO to BUSY_POLL_SO
   Rename sysctl_net_ll_{read,poll} to sysctl_busy_{read,poll}
   Fix up users of these variables.
   Fix documentation for sysctl.

v2 fixed forgetting the ndo changes in v1
v3 is a resend with -M
====================

-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.
