I had the same experience under NetBSD-1.4P.
I try and error, tlp driver works for me.

tlp driver clear sleep mode.but,do not clear for 21143.

My dmesg messages is below:
tlp0 at pci0 dev 9 function 0: DECchip 21143 Ethernet, pass 4.1
tlp0: interrupting at irq 11
tlp0: Ethernet address 00:00:39:03:2b:15
