rG1e6131bad6b4: IfAPI: Add needed APIs for mbuf support

Summary

Add 2 new APIs for supporting recent mbuf changes:

36e0a362ac added the m_snd_tag_alloc() wrapper around if_snd_tag_alloc(). Push this down to the ifnet level.
4d7a1361ef adds the m_rcvif_serialize()/m_rcvif_restore() KPIs to serialize and restore an ifnet pointer. Add the necessary wrapper to get the index generation for this.

1589	Not sure if it's better to just flat remove m_snd_tag_alloc() in this case. Thoughts?

1589	It might very well be. I would perhaps do that as a separate followup though after this commit.
