This cycle saw a focus on rxe and bnxt_re drivers:
 
 - Code cleanups for irdma, rxe, rtrs, hns, vmw_pvrdma
 
 - rxe uses workqueues instead of tasklets
 
 - rxe has better compliance around access checks for MRs and rereg_mr
 
 - mana supportst he 'v2' FW interface for RX coalescing
 
 - hfi1 bug fix for stale cache entries in its MR cache
 
 - mlx5 buf fix to handle FW failures when destroying QPs
 
 - erdma HW has a new doorbell allocation mechanism for uverbs that is
   secure
 
 - Lots of small cleanups and rework in bnxt_re
    * Use the common mmap functions
    * Support disassociation
    * Improve FW command flow
 
 - bnxt_re support for "low latency push", this allows a packet
