Fwd: Ask for suggestions: Is it practical for me, a mediocre programmer, to implement the support of `IPV6_TCLASS` control for Hurd?

Thank you, Samuel.


    In your opinion, it's feasible to add a support to `IPV6_TCLASS` 
for GNU Hurd by contributing to `lwIP` which will be migrated to

GNU Hurd and replaced `pfinet`.  Isn't it?  Thank you very much for your 
help!  I decide to give it a try!
