Date: Mon, 26 Feb 2007 11:06:32 -0800 From: Ron Mercer <ron.mercer@...gic.com> To: jeff@...zik.org Cc: ron.mercer@...gic.com, romieu@...zoreil.com, benjamin.li@...gic.com, netdev@...r.kernel.org Subject: [PATCH 02/13] qla3xxx: Remove unnecessary memset() in qla3xxx_send() From: Benjamin Li <benjamin.li@...gic.com> 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.
