[PATCH 5.10.y-cip 27/61] ravb: Factorise ravb_adjust_link function


Lad Prabhakar
 

From: Biju Das <biju.das.jz@...>

commit cb21104f2c35c97a1c803c48f26ad99ff5c5c9d4 upstream.

R-Car supports 100 and 1000 Mbps transfer speed whereas RZ/G2L
in addition support 10Mbps. Factorise ravb_adjust_link function
in order to support 10Mbps speed.
