This tells me that all the dropped packets are occurring in the iSCSI

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

We have newer firmware that will not include dropped iSCSI packets in
the networking counters.  It should appear in the 2.6.33 kernel
