On GENERIC kernel, 9.0 i386, the rl0 card 

a) isn't detected for install (boot off CD)

b) after install, it is detected and works, but link keeps bouncing.

Card info:

rl0@pci0:1:6:0: class=0x020000 card=0x7148109f chip=0x813910ec rev=0x10 hdr=0x00
    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL-8139/8139C/8139C+'
    class      = network
    subclass   = ethernet
    cap 01[50] = powerspec 2  supports D0 D1 D2 D3  current D0


in messages (when sending data though nic):

rl0: link state changed to DOWN
rl0: link state changed to UP
rl0: link state changed to DOWN
rl0: link state changed to UP
rl0: link state changed to DOWN
rl0: link state changed to UP
rl0: link state changed to DOWN
rl0: link state changed to UP

Fix: 

unknown.  Temporarily using different nic.
How-To-Repeat: Install 9.0 and send data over the rl0 link.

State Changed
From-To: open->feedback

Try set the following loader tunable in /boot/loader.conf and let 
me know whether that change makes any difference. 

dev.rl.0.twister_enable="1"
