Subject: [net-next-2.6 PATCH] ixgbe: DCB: remove DCB check config

From: John Fastabend <john.r.fastabend@...el.com>

Remove a DCB check config from DCB configuration we
continue to configure DCB even if it fails so don't
even bother to check.  Plus user space (lldpad) checks
this before programming the hw anyways.

Worse case is we program some values into the hw that
don't make total sense resulting in incorrect bandwidth
allocation.
