As an addendum, I just used "ethtool" in order to turn off NIC-based 
checksumming on the bonded interface and then tried tcpdump again on the 
FTP real server. This time, all the checksums came back as "correct".

So the checksums are correct. I was suspicious that all of the outgoing 
packets had bad checksums - particularly seeing as port 21 also had 
this, yet the FTP commands besides uploading work fine - so I thought 
I'd remove the possibility of it being NIC-based checksumming causing it 
and see if there's any packets left as "incorrect" afterwards ("grep 
incorrect").

There isn't. All the checksums are fine.

Regards,
Owain
