From a91fb143de61dce847e319ca79b9937a665ad622 Mon Sep 17 00:00:00 2001 From: Jan-Bernd Themann Date: Tue, 15 Jun 2010 05:35:16 +0000 Subject: [PATCH] ehea: fix delayed packet processing In the eHEA poll function an rmb() is required. Without that some packets on the receive queue are not seen and thus delayed until the next interrupt is handled for the same receive queue.
