ethtool: (uapi) Add ETHTOOL_PHY_DOWNSHIFT to PHY tunables
|
|
|
149f89 |
|
|
|
149f89 |
For operation in cabling environments that are incompatible with
|
|
|
149f89 |
1000BASE-T, PHY device may provide an automatic link speed downshift
|
|
|
149f89 |
operation. When enabled, the device automatically changes its 1000BASE-T
|
|
|
149f89 |
auto-negotiation to the next slower speed after a configured number of
|
|
|
149f89 |
failed attempts at 1000BASE-T. This feature is useful in setting up in
|
|
|
149f89 |
networks using older cable installations that include only pairs A and B,
|
|
|
149f89 |
and not pairs C and D.
