This does not matter.
A change would require patching net/ipv4/tcp_bbr.c , and the 'const'
attribute being there or not does not prevent the change.
I was simply asking to Stephen if the compiler would actually emit a
very different code, worth doing a last minute change.
The main BBR costs are divides and some multiplies , and they are
using per socket fields.
