Thanks.
Frames sent by the host running Wireshark are not guaranteed to be padded at all,
so they might appear to be less than 60 bytes long; they will also not include the CRC. That's because a copy of the packet is provided to the mechanism libpcap/WinPcap uses, and thus to the application using libpcap/WinPcap - for example, Wireshark - directly in software, bypassing the network adapter and thus bypassing the CRC calculation and perhaps even bypassing the padding.
Now I understand. The report of xx bytes on *wire* by wireshark just 
confused me a lot.
Kiran.
