Change 155798 by weongyo at weongyo_ws on 2009/01/08 03:55:24

	As a looking of the Realtek's linux driver they use RX_MAXSIZE buffers
	with 0x9c4(2500) but currently urtw(4) would use MCLBYTES.  Without
	datasheets it looks hard to define the value exactly.  Just with some
	testing it looks it's ok to use MCLBYTES but not sure there're some
	side-effects.
	
	So temporary remove a warning message to make users into confusions.
