Subject: qed: Introduce iWARP personality
Patch-mainline: v4.13-rc1
Git-commit: c851a9dc4359c6b19722de568e9f543c1c23481c
References: bsc#1050536 FATE#322898 bsc#1050545 FATE#322893
iWARP personality introduced the need for differentiating in several
places in the code whether we are RoCE, iWARP or either. This
leads to introducing new macros for querying the personality.
