Affected in what way? 

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" ?

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?
