Looks like, after that commit, I can't use if_ath loaded as module any
more:
# kldload /boot/kernel/ath_rate.ko
kldload: can't load /boot/kernel/ath_rate.ko: No such file or directory
# dmesg | tail -n1
link_elf: symbol ath_hal_computetxtime undefined
#
Yes, I've read UPDATING entry 20081130.
But I have no ath_hal entry in my kernel config,
I've loaded ath as KLDs.
How to fix that problem ?
