 - Minor cleanups: coding style, useless includes and documentation

 - Reorganize how multicast processing works in rxe

 - Replace a red/black tree with xarray in rxe which improves performance

 - DSCP support and HW address handle re-use in irdma

 - Simplify the mailbox command handling in hns

 - Simplify iser now that FMR is eliminated
