From 352f76879ebde543817360ce9c18c973d4300f4f Mon Sep 17 00:00:00 2001 From: Michael Chan Date: Fri, 2 May 2008 16:57:26 -0700 Subject: bnx2: Zero out context memory for 5709. We should zero out the context memory for 5709 before each reset. When we resume after suspend for example, the memory may not be zero and the chip may not function correctly.
