cd /sys/modules/ath_rate_amrr

kldload /boot/kernel/ath_rate .ko
It works now, but why three directories in sys/modules tree make
same .ko object:
# fgrep ath /sys/modules/Makefile
ath \
ath_rate_amrr \
ath_rate_onoe \
ath_rate_sample \
# fgrep KMOD /sys/modules/ath_rate*/Makefile
/sys/modules/ath_rate_amrr/Makefile:KMOD= ath_rate
/sys/modules/ath_rate_onoe/Makefile:KMOD= ath_rate
/sys/modules/ath_rate_sample/Makefile:KMOD= ath_rate
#
Looks like one overwrites another. What is right behaviour ?
