This series adds support for 64 bit per cpu stats and GRO
Patches 1-2 are cleanups of return code and a redundant condition
Patch 3 adds support for 64 bit per cpu stats
Patch 4 adds support for GRO using GRO cells
v1->v2: Since gro_cells_init() could potentially fail, move it from device
setup to ndo_init() as mentioned by Eric.

net: qualcomm: rmnet: Always assign rmnet dev in deaggregation path
net: qualcomm: rmnet: Add support for 64 bit stats

Since packet is always consumed by rmnet_rx_handler(), we always
return RX_HANDLER_CONSUMED. There is no need to pass on this
value through multiple functions.

The rmnet device needs to assigned for all packets in the
deaggregation path based on the mux id, so the check is not needed.
