Increasing this value 176# means sacrificing startup time and gathering more data wrt channel 177# interference that may help choosing a better channel. This can also help fine 178# tune the ACS scan time in case a driver has different scan dwell times. 179# 180# acs_chan_bias is a space-separated list of <channel>:<bias> pairs.

In other words, values between 0.0 and 1.0 can be used to 185# make a channel more likely to be picked while values larger than 1.0 make the 186# specified channel less likely to be picked.
