David, all, I'm about to resend this series (alternative to "ping"), 
however:

1/ Now that it's late in the cycle, I'd like that you tell me if I 
rebase on net-next because it isn't not sensible to queue such (non 
urgeent) changes at rc7

2/ I didn't get answers from Russell and can't tell if there's a better 
way of handling underlying phylink error of phylink_ethtool_set_wol() in 
patch 3/5

Best regards,
   Nicolas
