If it is feasible to bypass hang by tuning min_mem_kbytes,

No. Increasing or descreasing min_free_kbytes changes the timing but it
will still hang.

things may
become simpler if NICs are also tagged.

That would mean making changes to every driver and they do not necessarily
know what higher level protocol like TCP they are transmitting. How is
that simpler? What is the benefit?

The benefit is to avoid allocating sock buffer in softirq by recycling,
then the changes in VM core maybe less.

Thanks
