- This routine will detect what phy we are using, set the line
- speed, FDX or HDX, and configure the phy if necessary.
- The following combinations are supported:
- - TX or T4 PHY alone at PHY address 1
- - T4 or TX PHY at address 1 and MII PHY at address 0
- - 82503 alone (10Base-T mode, no full duplex support)
- - 82503 and MII PHY (TX or T4) at address 0
- The sequence / priority of detection is as follows:
- - PHY 1 with cable termination
- - PHY 0 with cable termination
- - PHY 1 (if found) without cable termination
- - 503 interface
- Additionally auto-negotiation capable (NWAY) and parallel
- detection PHYs are supported. The flow-chart is described in
- the 82557 software writer's manual.
- NOTE: 1. All PHY MDI registers are read in polled mode.
- 2. The routines assume that the 82557 has been RESET and we have
- obtained the virtual memory address of the CSR.
- 3. PhyDetect will not RESET the PHY.
- 4. If FORCEFDX is set, SPEED should also be set. The driver will
- check the values for inconsistency with the detected PHY
- technology.
- 5. PHY 1 (the PHY on the adapter) may have an address in the range
- 1 through 31 inclusive. The driver will accept addresses in
- this range.
- 6. Driver ignores FORCEFDX and SPEED overrides if a 503 interface
- is detected.
-
- @param AdapterInfo pointer to the structure that contains
- the NIC's context.
-
- @retval TRUE If a Phy was detected, and configured
- correctly.
- @retval FALSE If a valid phy could not be detected and
- configured.
