Subject: qed: Don't inherit RoCE DCBx for V2
Patch-mainline: v4.13-rc1
Git-commit: 38b23e43ee6f0903de989913884a2142bf8b3d7c
References: bsc#1050536 FATE#322898 bsc#1050538 FATE#322897

Older firmware used by device didn't distinguish between RoCE and RoCE
V2 from DCBx configuration perspective, and as a result we've used to
take a the RoCE-related configuration and apply to it for both.

Since we now support configuring each its own values, there's no reason
to reflect [& configure] that both are using the same.
