Subject: If_sip and FA311 checksum error

I put a brand new NetGear FA311 10/100 Ethernet board in a working 1.5.2
i386 NetBSD box (replacing a D-Link 530/TX card), using the generic kernel
and with /etc/ifconfig.sip0 installed and I get the following from dmesg:

sip0 at pci0 dev 9 function 0: NatSemi DP83815 10/100 Ethernet
sip0: interrupting at irq 10
sip0: Checksum (bf) mismatch (7f)sip0: Ethernet address 00:02:e3:18:ab:98
ukphy0 at sip0 phy 0: Generic IEEE 802.3u media interface

The Checksum error seems to be very serious.  I'm guessing the MAC address
is being read incorrectly.

Ifconfig sip0 reports:

        address: 00:02:e3:18:ab:98
        media: Ethernet autoselect (100baseTX full-duplex)
        status: active
        inet netmask 0xffffff00 broadcast
        inet6 fe80::202:e3ff:fe18:ab98%sip0 prefixlen 64 scopeid 0x1

I have link and activity lights and I can ping the board in a loop, but all
other net access is down.  A tcpdump reports problems with arp which makes
sense if the MAC is wrong.  I've also tried the 12/21/2001 current i386
kernel with the same results.

Before I brave the return line at Fry's can anyone suggest a solution?
