Reminder of this patch. This is waiting in the backlog for a long time. It is not even clear if the patch is still valid or not. Also based on missing response to Chas' clarification request, I am for dropping/rejecting the patch. @Declan, @Radu please chime in if this patch is required/valid. > > On Tue, Feb 6, 2018 at 3:52 PM, Thomas Monjalon > wrote: > > 17/01/2018 17:02, Ferruh Yigit: > > On 11/29/2017 3:42 PM, Tomasz Kulasek wrote: > > > Some devices needs more time to initialize and bring interface up.
