net: introduce struct net_hotdata
Instead of spreading networking critical fields
all over the places, add a custom net_hotdata
structure so that we can precisely control its layout.
In this first patch, move :
- gro_normal_batch used in rx (GRO stack)
- offload_base used in rx and tx (GRO and TSO stacks)
