Eric Dumazet a435163d31 net-sysfs: use rps_tag_ptr and remove metadata from rps_dev_flow_table
Instead of storing the @log at the beginning of rps_dev_flow_table
use 5 low order bits of the rps_tag_ptr to store the log of the size.

This removes a potential cache line miss (for light traffic).

This allows us to switch to one high-order allocation instead of vmalloc()
when CONFIG_RFS_ACCEL is not set.
