Affected in what way? 

They dont get errors back and they just keep sending even in the
presence of errors - take a look at ip_push_pending_frames. I have been
struggling initially to unconditionally mod that part, but it may break
certain apps expectations.

If you set that option though you end up getting all these skbs back

IP_RECVERR just delivers ICMPs. Do you mean those with "all these skbs" ?

yes - sorry thats what i meant; the app has to do a recvmsg to grab them

to the app which i see as unnecessary work if i am uninterested. I would
like to not do a recvmsg to find out what those messages are - rather
just receiving any errors back.
My proposal is to add another option which is mutually exclusive with
IP_RECVERR that allows for errors only.

What ICMPs do you not want? 

All.
