I'm trying to view some packets generated by a SmartBits.

I generate a 1514 byte frame on the Smart Bits. This goes out and
ethereal displays it. The device on the other end, loops it back
(Swaps Src & Dest MAC & IP Addrs.) The SmartBits capture tools
receives and displays the frame. Ethereal doesn't. There is one
slight modification to frame. Due to a hardware limitation on the
DUT, the return frame is now 1516 bytes (not including CRC.) We're
forced to use 4 byte alignment on our transmit. So the returned frame
is now over sized. I have witnessed v0.10.7 of Ethereal displaying
frames of this size, but 0.10.10 does not. I tried WireShark 0.99.3
and it doesn't display the over sized frames either.

I'm about to go research pcap/tcpdump to see if the problem lies there.

I really need to either configure Ethereal/WireShark/Pcap to display
these over sized frames or find a tool that does. Any help will be
appreciated. Thanks in advance.
