I changed the MAC address and gave the same address as sis's one (which should
be valid (what is a valid MAC address?) because the sis device's MAC address is
seen by the DG834Gv2) but it didn't change anything.

In the reference manual, I found a reference to ARP as general protocol
but it's not said explicitly that the DG834Gv2 use it:
ftp://downloads.netgear.com/files/dg834g_ref_manual.pdf
So I guess it's the protocol used.
