FYI-My understanding is that the TOE functionality in Broadcom's GbE
NetXreme controllers is only supported for Windows
(through the Windows 2003 Scalable Networking Pack 'Chimney'
TOE interface), for Linux NetXtreme only supports L2 NIC and iSCSI initiator

I stand corrected. :-)
For those of you as ignorant as I was of these particular NICs (although I
have been using them for some time), it appears after some research that all
the BCM5708 devices, whether by Broadcom or re-branded by OEMs, do support
both iSCSI and TOE in hardware, and RDMA as well. Even though the iSCSI
engine appears quite broken in its original incarnation, per Ben's
Thank you for that insight.
Ben, just for the record, can you give us your "lspci -nn | grep BCM5708"
