Hi Jose

You need to be careful here. There is a reason this is called
gen10g_no_soft_reset, rather than having an empty
gen10g_soft_reset. Some PHYs break when you do a reset.  So adding a
gen10g_soft_reset is fine, but don't change this here, without first
understanding the history, and talking to Russell King.
