From fff3321d75b1a18231876a1aceb36eacbbf6221e Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 16 Aug 2012 05:36:48 +0000 Subject: packet: Report fanout status via diag engine Reported value is the same reported by the FANOUT getsockoption, but unlike it, the absent fanout setup results in absent nlattr, rather than in nlattr with zero value. This is done so, since zero fanout report may mean both -- no fanout, and fanout with both id and type zero. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
