bad CRC (Cyclic Redundancy Check)

[Elneorojo <bigred@sunflower.com>]

OS Version: 2.6 patched
NIC's:  Cheap de* 10/100's  (standard DEC 21143)

Well i came home today to find that i had received a "bad crc" error on
the internal NIC on my LAN.  While receiving a bad crc does not happen
that often I was curious to know if this was due to the hardware not
being able to compute the frame in ? or if this can be duplicated. 
Simply put, I was wondering why the NIC (or the TCP/IP stack) was not
able to recover from computing the CRC value and continue normal
operation.  Any thoughts?
