After this you should be getting messages about packets being queued.
Here are message levels -- you'll need "debug=16" to see all of these.
	NETIF_MSG_DRV           = 0x0001,
	NETIF_MSG_PROBE         = 0x0002,
	NETIF_MSG_LINK          = 0x0004,
	NETIF_MSG_TIMER         = 0x0008,
	NETIF_MSG_IFDOWN        = 0x0010,
	NETIF_MSG_IFUP          = 0x0020,
	NETIF_MSG_RX_ERR        = 0x0040,
	NETIF_MSG_TX_ERR        = 0x0080,
	NETIF_MSG_TX_QUEUED     = 0x0100,
	NETIF_MSG_INTR          = 0x0200,
	NETIF_MSG_TX_DONE       = 0x0400,
	NETIF_MSG_RX_STATUS     = 0x0800,
	NETIF_MSG_PKTDATA       = 0x1000,
	NETIF_MSG_WOL           = 0x4000,
	NETIF_MSG_MISC          = 0x8000,
	NETIF_MSG_RXFILTER      = 0x10000,

You should see messages such as
   "eth0: Queuing Tx packet, index 0.\n"

Exactly.  The earlier line should match the 3c920 card we know about.
The second line will match future versions.

The "Zc" version of a mid-december added a line in the middle:
	{"3c920 Radeon Tornado",{ 0x920210B7, 0xffffffff },
	 PCI_IOTYPE, CYCLONE_SIZE, FEATURE_TORNADO, },
The only change is to specifically identify the NIC type -- the driver
does not change behavior.

If we find a need for a driver for this specific ID, the line might
change to something such as
	{"3c920 Radeon Tornado",{ 0x920210B7, 0xffffffff },
	 PCI_IOTYPE, CYCLONE_SIZE, FEATURE_TORNADO|WN0_XCVR_PWR, },
