From 0ef00459a638ae4f5d1e5326d3e50232fa80119f Mon Sep 17 00:00:00 2001 From: Eilon Greenstein Date: Wed, 14 Jan 2009 21:31:08 -0800 Subject: bnx2x: First slow path interrupt race The "read for interrupts" flag must be set before enabling slow-path interrupts as well (and not just before fast-path interrupts) Signed-off-by: Eilon Greenstein Signed-off-by: David S.
