If it is not documented at Intels site, the best bet is to look at the
source.

I _believe_ you can set the parameters of the e1000 with ethertool, or
you can use amongst others the following parameters at module load:

E1000_PARAM(RxDescriptors, "Number of receive descriptors");

/* User Specified Speed Override
 *
 * Valid Range: 0, 10, 100, 1000
 *  - 0    - auto-negotiate at all supported speeds
 *  - 10   - only link at 10 Mbps
 *  - 100  - only link at 100 Mbps
 *  - 1000 - only link at 1000 Mbps
 *
 * Default Value: 0
 */


E1000_PARAM(Speed, "Speed setting");

/* User Specified Duplex Override
 *
 * Valid Range: 0-2
 *  - 0 - auto-negotiate for duplex
 *  - 1 - only link at half duplex
 *  - 2 - only link at full duplex
 *
 * Default Value: 0
 */

E1000_PARAM(Duplex, "Duplex setting");

/* Auto-negotiation Advertisement Override
 *
 * Valid Range: 0x01-0x0F, 0x20-0x2F (copper); 0x20 (fiber)
 *
 * The AutoNeg value is a bit mask describing which speed and duplex
 * combinations should be advertised during auto-negotiation.
 * The supported speed and duplex modes are listed below
 *
 * Bit           7     6     5      4      3     2     1      0
 * Speed (Mbps)  N/A   N/A   1000   N/A    100   100   10     10
 * Duplex                    Full          Full  Half  Full   Half
 *
 * Default Value: 0x2F (copper); 0x20 (fiber)
