Hi Baptiste,
I have added GRE support (gre/gretap/grev6/grev6tap) in netifd which I'm
currenlty testing. The implementation looks the same as for 6rd/dslite tunnel
interfaces (thus allowing to set mtu/ttl/remote end point); additonally it
allows to set gre specific parameters (ikey/okey/iseq/oseq/...)
I'm planning to submit the patches in one of the next weeks.
Regards,
Hans
