We have recently enabled iSCSI in the kernel and you probably don't have the userspace components to handle the iSCSI ring. All broadcast packets are also received in the iSCSI ring and they are all dropped in this case without the userspace components. Networking is not affected. If you rmmod the bnx2i and cnic drivers, the drop counter should stop counting. We have newer firmware that will not include dropped iSCSI packets in the networking counters. It should appear in the 2.6.33 kernel time-frame.
