            Bug ID: 193743
           Summary: RTL8111/8168B PCI Express Gigabit Ethernet controller:
                    doesn't work properly, problems getting UP
                    automatically
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: amd64
                OS: Any
            Status: Needs Triage
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org

Running FreeBSD 11.0-CURRENT (11.0-CURRENT #5 r271728: Thu Sep 18 01:18:25 CEST
2014 amd64) on a Lenovo ThinkPad Edge E540 laptop, 
CPU: Intel(R) Core(TM) i5-4200M CPU @ 2.50GHz (2494.28-MHz K8-class CPU), the
built-in LAN adaptor doen't work correctly as it doesn't get up automatically. 


Symptoms:

After booting the system, the OS does recognise the NIC properly and
initializes the hardware. But then, the NIC is "dead" or down - no connection.
Carrier is "active". Sometimes - sporadically - DHCP offers/requests where
fullfilled, but then the NIC is "dead".

Solution:

After the box and NIC is up, turning the NIC down and then up and waiting a
second or two makes the NIC working as expected.

This phenomenon occurs on different types of switches (Netgear, HP Procurve,
Cisco). 


The hardware reveals itself to the OS as

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500  
options=8219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,LINKSTATE>

and
