1 Certain SFP modules (most notably Nokia GPON ones) first check
2 connectivity on 1000base-x, and switch to 2500base-x afterwards. This
3 is considered a quirk so the phylink switches the interface to
6 However, after power-cycling the uDPU device, network interface/SFP module
7 will not work correctly until the module is re-seated. This patch
8 resolves this issue by forcing the interface to be brought up in
9 2500base-x mode by default.
