The STLab N-313 PCI-e NIC have RTL8111/8168/8411 chipsets, not RTL8111/8168B.

This card (same VendorID, rev. 01, integrated on a Giga-byte Technology GA-EP45-DS5 Motherboard [1458:e000]) works very badly when coupled in the same system with a separate D-Link System Inc DGE-528T Gigabit Ethernet Adapter [1186:4300] (rev 10).

The Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 0b) is included in the Acer Z5771 computer.

According to manufacturer, revision 12, that is integrated in the ASUS F550JK-DCM1120 netbook, is 8168C, not 8168B

As for kernel 3.11.0-18-generic Flow Control can't be disable on this NIC
