Hi all,

Will the CCA string in setsockopt and getsockopt for TCP_CONGESTION always
be lowercase?

I am not aware of any such guarantee. From kernel's point of view, it is just
a simple string search in /proc/sys/net/ipv4/tcp_available_congestion_control,
so in the future we may add CCA with upper cases. And, since CCA can be
a kernel module, maybe there are already OOT modules using upper case
names.

Thanks.
