From d2d76b8db4e681944801870f81b859c5bf9964cf Mon Sep 17 00:00:00 2001 From: Benjamin Li <benjamin.li@qlogic.com> Date: Mon, 26 Feb 2007 11:06:32 -0800 Subject: [PATCH] qla3xxx: Remove unnecessary memset() in qla3xxx_send() We do not need to zero out the 64 byte MAC request I/O control block. By zeroing out the control block and setting it to proper fields is redundant work. This is because in the qla3xxx_send() function we will already set the proper fields in this structure. The unused fields are not looked at by the hardware and do not need to be zeroed out.
