Hi Jakub -

The conflict here is purely in the diff context, patch 2 of this series 
and "tcp: socket option to check for MPTCP fallback to TCP" add cases to 
the same switch statement and have a couple of unmodified lines between 
their additions.

"git am -3" handles it cleanly in this case, if you have time and 
inclination for a second attempt. But I realize you're working through a 
backlog and net-next is now closed, so that time might not be available. 
We'll try again when net-next reopens if needed.


Thanks,
Mat
