Subject: [PATCH] [SCSI] fnic: Replace memset with eth_broadcast_addr

Use eth_zero_addr to assign the zero address to the given address
array instead of memset when second argument is a broadcast
address 0xff.

The Coccinelle semantic patch that makes this change is as follows:

// <smpl>
@eth_broadcast_addr@
identifier e;
@@

-memset(e,\(0xff\|0xFF\|255\),ETH_ALEN);
+eth_broadcast_addr(e);
// </smpl>
