1000 (gigE) adapter duplex

[enterprisebu]

I've installed a gigE card and have these two device drivers but I do not get the 1000 full option through smit and my command line dev change is rejecting. What am I missing?
devices.pci.14106802.rte 5.2.0.10 COMMITTED Gigabit Ethernet-SX PCI-X
devices.pci.14106902.rte 5.2.0.30 COMMITTED 10/100/1000 Base-TX PCI-X

the (only) valid option for gigabit is autonegotiation.

it is written in manual.

That is just something I couldn't believe. I know that setting auto should enable 1000 full BUT we use Netbackup and it drops packets on auto. Oh, bother!

For "Gigabit Ethernet-SX PCI-X Adapter" you should have an 1000Mbit media_speed option, but for "10/100/1000 Base-TX PCI-X" the only valid seems to be Auto-negotioation for gigabit - below is the info for this adapter.

Media Speed
The media speed attribute indicates the speed at which the adapter will attempt to operate. The available speeds are 10 Mbps half-duplex, 10 Mbps full-duplex, 100 Mbps half-duplex, 100 Mbps full-duplex and auto-negotiation, with a default of auto-negotiation. Select auto-negotiate when the adapter should use auto-negotiation across the network to determine the speed. When the network will not support auto-negotiation, select the specific speed.
Note:
1000 MBps half and full duplex are not valid values. As per the IEEE 802.3z specification, gigabit speeds of any duplexity must be auto-negotiated for copper (TX) based adapters. Please select auto-negotiation if these speeds are desired.
