Subject: [PATCH] net: mvneta: Add 2500BaseT support
|
||
|
|
|
||
|
|
Some PHYs will use the 2500BaseX PHY_INTERFACE_MODE when being linked
|
||
|
|
with a partner using 2.5GBaseT.
|
||
|
|
|
||
|
|
Since we can't autonegotiate this speed between the MAC and the PHY, we
|
||
|
|
need to have the proper comphy support enabled, to make sure we can
|
||
|
|
safely advertise 2.5G and 1G in BaseT and be able to switch between both
|
||
|
|
corresponding PHY interface modes. This is now possible since comphy
|
||
|
|
support was added to this driver.
|
||
|
|
|
||
|
|
This commit adds the 2500BaseT mode to the list of supported modes when
|
||
|
|
using 2500BaseX, and was tested on a setup with an Armada385 and a
|
||
|
|
88E2010 PHY, both with and without the comphy node in the DT.
