Error loading tcp_bbr kernel module

[Gordon Bergling]

Greetings,

I build -CURRENT with WITH_EXTRA_TCP_STACKS=1, but I got the following error
when I try to load for example tcp_bbr.ko.

kldload: an error occurred while loading module tcp_rack.ko. Please check dmesg(8) for more details.

dmesg shows:

KLD tcp_bbr.ko: depends on tcphpts - not available or version mismatch
linker_load_file: /boot/kernel/tcp_bbr.ko - unsupported file type

Any hints on solving the problem?

The kernel config is GENERIC.

Best regards,

Gordon
