Not really, no. Here are a few quotes from the book:

Quote:
Note According to IEEE 802.3 specifications, when using 1000 Mbps speed over
copper media, autonegotiation is not optional. In the absence of autonegotiation, (for
example, while using Forced mode), link syncing between link partners may not
happen and the link may not come up.


To Set Autonegotiation to off for Other Noncompliant Network Equipment
If your network equipment does not support autonegotiation, you can set
autonegotiation to off on the GigaSwift Ethernet (ce) device.
1. Set the following GigaSwift Ethernet driver parameters to values according to the
documentation that shipped with your switch:
* adv-1000fdx-cap
* adv-1000hdx-cap
* adv-ampause-cap
* adv-pause-cap
2. Set the adv-autoneg-cap parameter to 0.


When link-up is attempted with autonegotiation enabled (the default), the link parameter capabilities (such as speed in megabits/second, duplex and link-clock mastership only for 1000 Mbps) are automatically negotiated between the device and its link partner.

The concept of link clock mastership was introduced with gigabit twisted-pair technology. One side of the link is the master that provides the link clock and the other side is the slave that uses the link clock. Once this relationship is established, the link is up, and data can be communicated. Two physical layer parameters control whether your side is the master or the slave, or whether mastership is negotiated with the link partner....
I gather that following the documentation is not your style, you don't seem too interested in the advice to turn on auto-negotiation. When I see language like the above, I do turn it on. I don't know what happens when you run without it. Good luck with the pause and clock mastership stuff. Since you're a network dude I assume you have it all under control.

Anyway here is another quote from the book...
Quote:
Note: Configuring the parameters by putting ndd commands in rcX.d scripts is
not supported.
So what happens if you do? Gosh, Andy, I don't know. But based on your report, I'm not missing much.

rge

rge(7D) 							      Devices								   rge(7D)

NAME

       rge - Realtek Gigabit/Fast Ethernet Network Adapter driver

SYNOPSIS

       /dev/rge

DESCRIPTION

       The  rge  Gigabit/Fast  Ethernet  driver  is  a multi-threaded,	loadable,  clonable,  GLD-based  STREAMS  driver supporting  the Data Link
       Provider Interface, dlpi(7P), on  the Realtek Gigabit/Fast Ethernet Network Adapter.

       The rge driver functions includes controller initialization, frame transmit and receive,  promiscuous  and  multicast  support,	and  error
       recovery and reporting.

APPLICATION PROGRAMMING INTERFACE

       The cloning,  character-special device /dev/rge is  used to access all Realtek Gigabit/Fast Ethernet devices installed within the system.

       The  rge  driver  is  managed  by the dladm(1M) command line utility, which allows VLANs to be defined on top of rge  instances and for rge
       instances to be aggregated. See dladm(1M) for more details.

       The values returned by the driver in the DL_INFO_ACK primitive in response to the DL_INFO_REQ are as follows:

	   o	  Maximum SDU (with jumbo frame) is 7000.

	   o	  Minimum SDU is 0.

	   o	  DSLAP address length is 8 bytes.

	   o	  MAC type is DL_ETHER.

	   o	  SAP length value is  -2, meaning the physical address component is followed immediately by a 2-byte  sap  component  within  the
		  DLSAP address.

	   o	  Broadcast address value is Ethernet/IEEE  broadcast address (FF:FF:FF:FF:FF:FF).

       Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.

CONFIGURATION

       By  default,  the rge driver performs auto-negotiation to select the link speed and mode. Link speed and mode can be any one of the follow-
       ing:

	   o	  1000 Mbps, full-duplex

	   o	  100 Mbps, full-duplex

	   o	  100 Mbps, half-duplex

	   o	  10 Mbps, full-duplex

	   o	  10 Mbps, half-duplex

       Alternatively, you can set the capabilities advertised by the rge device using ndd(1M). The driver supports a number  of  parameters  whose
       names  begin  with adv_. Each of these parameters contains a boolean value that determines if the device advertises that mode of operation.
       The adv_pause_cap indicates if half/full duplex pause is advertised to link partner. You can set adv_asym_pause_cap  to	advertise  to  the
       link partner that asymmetric pause is desired.

       For example, to prevent the device 'rge2' from advertising gigabit capabilities, enter (as super-user):

	 # ndd -set /dev/rge2 adv_1000fdx_cap 0

       All capabilities default to enabled. Note that changing any capability parameter causes the link to go down while the link partners renego-
       tiate the link speed/duplex using the newly changed capabilities.

       You can find the current parameter settings by using ndd -get. In addition, the driver exports the current state,  speed,  duplex  setting,
       and  working  mode  of the link via ndd parameters (these are read only and may not be changed). For example, to check link state of device
       rge0:

	 # ndd -get /dev/rge0 link_status
	 1
	 # ndd -get /dev/rge0 link_speed
	 100
	 # ndd -get /dev/rge0 link_duplex
	 2

       The output above indicates that the link is up and running at 100Mbps full-duplex. In addition, the driver  exports  its  working  mode	by
       loop_mode. If it is set to 0, the loopback mode is disabled.
