First -rc update for 4.14 kernel

Browse source 
- Smattering of miscellanous fixes
 - A five patch series for i40iw that had a patch (5/5) that was larger
   than I would like, but I took it because it's needed for large scale
   users
 - An 8 patch series for bnxt_re that landed right as I was leaving on
   PTO and so had to wait until now...they are all appropriate fixes for
   -rc IMO
