MAC address matching with M5223X

Hi All

I was playing around with the M52235EVB today.

I set several MAC addresses and checked that ARP, ping  and an embedded web server were working correctly.

These are the addresses which I used:

00-00-00-00-00-00
00-00-00-00-00-11
00-00-00-00-11-22
00-00-11-22-33-44
00-11-22-33-44-55
11-22-33-44-55-66
66-55-44-33-22-11

In each case ARP works fine. The device responds to the broadcast with its MAC address (as shown in the list) and the PC then displays the IP/MAC combination in its ARP table (I delete the ARP table in the PC with arp -d between tests)

In each case pings and the web browser operate correctly with the exception of the MAC address 11-22-33-44-55-66. No frames are received with the MAC destination, only broadcasts.

Can any one reproduce this or explain why the one address (or some sort of combinations) would not work?

Many thanks for ideas.
