Nevermind.  Just tried it with Solaris Nevada build 16 and it works
too!  

Albeit with some minor caveats.  For instance, a broadcast ping from
Linux does not see the Solaris node:

This is a linux system:

[root at sins-stinger-10 ~]# ping 192.168.0.0 -b
WARNING: pinging broadcast address
PING 192.168.0.0 (192.168.0.0) 56(84) bytes of data.
64 bytes from 192.168.0.233: icmp_seq=0 ttl=64 time=0.054 ms
64 bytes from 192.168.0.26: icmp_seq=0 ttl=64 time=0.159 ms (DUP!)
64 bytes from 192.168.0.233: icmp_seq=1 ttl=64 time=0.016 ms
64 bytes from 192.168.0.26: icmp_seq=1 ttl=64 time=0.114 ms (DUP!)

From the Solaris system:

[root at nisus ~]# ping -s 192.168.0.0
PING 192.168.0.0: 56 data bytes
64 bytes from 192.168.0.78: icmp_seq=0. time=0.501 ms

64 bytes from 192.168.0.26: icmp_seq=0. time=10.4 ms

Solaris 10 was unhappy:

[root at blissom ~]# ifconfig ibd0 plumb
ifconfig: SIOCSLIFNAME for ip: ibd0: no such interface
Jun  7 15:29:02 blissom.SFBay.Sun.COM ip: ibd0: DL_ATTACH_REQ failed: DL_BADPPA
Jun  7 15:29:02 blissom.SFBay.Sun.COM ip: ibd0: DL_BIND_REQ failed: DL_OUTSTATE
Jun  7 15:29:02 blissom.SFBay.Sun.COM ip: ibd0: DL_PHYS_ADDR_REQ failed: DL_OUTSTATE
Jun  7 15:29:02 blissom.SFBay.Sun.COM ip: ibd0: DL_UNBIND_REQ failed: DL_OUTSTATE

Which made my Nevada box unhappy:

< from dmesg >
interface ibd0 to 192.168.0.78 broken: in=3 ierr=0 out=5 oerr=2
