machine is an alpha 164LX running a 1.5S kernel.

>Description:
Machine with a tlp card that worked fine with the de driver in 1.4.2, probes
and panics as follows:
tlp0 at pci0 dev 6 function 0: DECchip 21140A Ethernet, pass 2.2
tlp0: interrupting at eb164 irq 0
tlp0: Ethernet address 00:40:05:a3:4d:08
tlp0: unable to configure MII
tlp0: no media found!

# ifconfig -a
tlp0: flags=8802panic: tlp_2114x_isv_tmsw_get
Stopped in pid 8 (ifconfig) at  cpu_Debugger+0x4:       ret     zero,(ra)

Older (1.4.2) kernel probed as follows:
de0 at pci0 dev 6 function 0
de0: interrupting at eb164 irq 0
de0: 21140A [10-100Mb/s] pass 2.2
de0: address 00:40:05:a3:4d:08
de0: enabling 100baseTX port

	
>How-To-Repeat:
Boot, type ifconfig, lose.
	
>Fix:
ENOCLUE.. assuming the workaround is to use the de driver for now.
