Patch should not hijack LAGG_PROTO_ETHERCHANNEL. Apart that it looks fine.

I agree with Gleb. I have noted in D539 that LAGG_PROTO_ETHERCHANNEL should be kept for compatibility.

Hello guys,

Finally I had time to finish this patch, as Glebius and Thompsa mention, this new patch does not hijack the FEC protocol, and we keep it as it is, just add a new protocol options 'broadcast'.

Looking forward for your review and approval.

Best Regards,

Isn't it possible to drop new patch on top of old one in this review system?

Maybe is possible to remove the old patch entirely and attache this one. I can try!
