K64 ENET TXF vs TXB

I'm getting a TXB and not a TXF interrupt flag being set at random times.

 

I can't find any documentation that would explain why.

 

TXF fires when the message has been sent.

 

TXB fires when the enhanced buffer has been updated.

 

So under what circumstances would I expect a buffer update but not a complete transmission?

 

Thanks for any comments
