Message-Id: <1320745197-11053-1-git-send-email-ricardo.ribalda@gmail.com> Date: Tue, 8 Nov 2011 10:39:57 +0100 From: Ricardo Ribalda Delgado <ricardo.ribalda@...il.com> To: davem@...emloft.net, ian.campbell@...rix.com, eric.dumazet@...il.com, jeffrey.t.kirsher@...el.com, jpirko@...hat.com, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Ricardo Ribalda Delgado <ricardo.ribalda@...il.com> Subject: [PATCH] net/ll_temac: FIX : Wait for indirect wait to end While tracing down a connectivity problem on the temac I connected a probe to the Cross bar irq, and it was triggered when doing ifdown->ifup. This is fixed once waiting for the indirect write to end. Since it is not on the hot path there is no performance loss.
