Certain SFP modules (most notably Nokia GPON ones) first check
|
|
connectivity on 1000base-x, and switch to 2500base-x afterwards. This
|
|
is considered a quirk so the phylink switches the interface to
|
|
2500base-x as well.
|
|
|
|
However, after power-cycling the uDPU device, network interface/SFP module
|
|
will not work correctly until the module is re-seated. This patch
|
|
resolves this issue by forcing the interface to be brought up in
|
|
2500base-x mode by default.
