msm: net: rndis: RNDIS LAN network interface driver API declarations 



Declaration file for rndis_ipa network interface.
Allows LAN network with RNDIS tethered Host.
Data transfer shall be based on Ethernet packets
with RNDIS framing between tethered HOST and embeded Apps.
IPA Core shall be used for Data path.
This change shall allow MIPS offload from Apps core.

merging in commit 6142c1e9  again
as it was removed as part of unused files removal.
