Make this option more sensible by only bypassing TX softirq wakeup and
remove
CONFIG_NETPOLL_RX option completely since there is *no* code depending
on it.

ACK but (a) DaveM not me should apply this,
Oops, sorry. But he's only mentioned as IPv4/v6 maintainer. :-)
and (b) I would check with
netpoll people to see what that define is there for.
Amit Kale and I were already asking about CONFIG_NETPOLL_TRAP here 1+
months ago and got no replies. Well I'll try to CC Matt Mackall...
If you mean CONFIG_NETPOLL_RX, there was #ifdef's in the early version of
netpoll support:
http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commitdiff;h=8fb9cf8ab6c0ccb1b17b32c05dc9da3cc96ac229
but later they were removed but the option left:
