Eric Dumazet suggested to allow users to modify max GRO packet size.
We have seen GRO being disabled by users of appliances (such as
wifi access points) because of claimed bufferbloat issues,
or some work arounds in sch_cake, to split GRO/GSO packets.
Instead of disabling GRO completely, one can chose to limit
the maximum packet size of GRO packets, depending on their
latency constraints.
This patch adds a per device gro_max_size attribute
that can be changed with ip link command.
ip link set dev eth0 gro_max_size 16000

Move gro code and data from net/core/dev.c to net/core/gro.c
to ease maintenance.
gro_normal_list() and gro_normal_one() are inlined
because they are called from both files.

net/core/gro.c will contain all core gro functions,
