>Description:
	ath(4) multicast filter is broken.

	I can output a packet via ath0. but I can NOT get any packet
	from ath0 (incl broadcast packet).

	With ath_debug=1, I got this message,
	> ath_mode_init: RX filter 0x17, MC filter 00000000:00000000
	I thought MC filter is not setup correctly.

	ath.c::ath_mcastfilter_*() may be wrong.
>How-To-Repeat:
	Use ath(4).
>Fix:
	This is very dirty patch. But it solves my problem.
	(It sets MC filter to ffffffff:ffffffff)
