From f78c0850d2ebe7a44a4b0263480a2f1a36a92218 Mon Sep 17 00:00:00 2001 From: Amit Kumar Salecha Date: Fri, 11 Sep 2009 11:28:11 +0000 Subject: [PATCH] netxen: change firmware write size Use 8 byte strides for firmware download into card memory since oncard memory controller needs 8 byte (64 bit) accesses. This avoids unnecessary rmw cycles. Signed-off-by: Amit Kumar Salecha Signed-off-by: Dhananjay Phadke Signed-off-by: David S.
