From 877364e60edeea06efa8ceb9d29201f195af8a47 Mon Sep 17 00:00:00 2001 From: Brice Goglin Date: Mon, 7 Jan 2008 22:09:08 -0800 Subject: [LRO] Fix lro_mgr->features checks lro_mgr->features contains a bitmask of LRO_F_* values which are defined as power of two, not as bit indexes. They must be checked with x&LRO_F_FOO, not with test_bit(LRO_F_FOO,&x). Signed-off-by: Brice Goglin Acked-by: Andrew Gallatin Signed-off-by: David S.
