David,

If the following names changes are acceptable I will try to send out
a patch today.

1. include/net/ll_poll.h -> include/net/busy_poll.h

2. ndo_ll_poll -> ndo_busy_poll

- not technically accurate since the ndo callback does not itself busy
poll, it's just used to implement it.

maybe ndo_napi_id_poll? or ndo_id_poll? I don't really like any of them,
so a suggestion would be nice.

3. sysctl_net_ll_{read,poll} -> sysctl_net_busy_{read,poll}
- along with matching file name changes.

4. {sk,skb}_mark_ll -> {sk,skb}_mark_napi_id

5. LL_SO -> BUSY_POLL_SO

Are you OK with the names?
Did I miss anything?

Thanks,
Eliezer
