3c59x.c:v0.99L 5/28/99 and problem with 3c905C

[Dusan Vujosevic]

Hi,

I asked the same question yesterday and here is Donald Becker's response:

>This is harmless, as long as it happens on the new 3c905C cards.  It exists
>because 3Com continues to stuff more info into the EEPROM.  Rather than
>computing a checksum over the whole EEPROM, or having a
backwards-compatible
>subset and retaining the old checksum location, they keep moving the
>checksum word a few bytes at a time.

>The "solution" in the updated drivers is to just omit the warning with new
>cards.  I've never seen a report of EEPROM that became spontaneously
>corrupted.
