net_sched: sfq: allow divisor to be a parameter
SFQ currently uses a 1024 slots hash table, and its internal structure
(sfq_sched_data) allocation needs order-1 page on x86_64
Allow tc command to specify a divisor value (hash table size), between 1
and 65536.
If no value is provided, assume the 1024 default size.
This allows admins to setup smaller (or bigger) SFQ for specific needs.
This also brings back sfq_sched_data allocations to order-0 ones, saving
3KB per SFQ qdisc.
Jesper uses ~55.000 SFQ in one machine, this patch should free 165 MB of
memory.
