Subject: [PATCH 3.12 09/58] ixgbe: use correct FCoE DDP max check

From: Vasu Dev <vasu.dev@...el.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit f10166aba2def9bc6443290231c60f7e2f70129b upstream.

Use fcoe_ddp_xid from netdev as this is correctly set for different
device IDs to avoid DDP skip error on X550 as "xid=0x20b out-of-range"
