: No, that is absolutely not correct. The checksum problems happend in many

100% confirmation here. When Bill Paul was tracking down these issues
on my 2550's they were all operating normally, without any vlan tagging.
The broadcom chips are horrendously buggy. The phase of the moon is as
likely to cause a problem as anything else. The on-chip checksum code
is especially bad. It's a classic example of rushing a chip into
production and praying that the hardware is flexible enough that
problems can be fixed in software by the driver.
