As far as the Airpcap code being Windows-specific: we've tried to
generalize it so that it can be adapted to other platforms.  There's no
reason the code that calls airpcap_if_set_device_channel() under Windows
can't (and shouldn't) use the SIOCSIWFREQ ioctl under Linux.
...at least with drivers that support the wireless extension.

Similarly, it could use the SIOCS80211 ioctl, with IEEE80211_IOC_CHANNEL, under BSDs.
At some point, in my Copious Free Time(TM), I'd like to get libpcap to 
support setting arbitrary properties on an open pcap_t, including the 
channel on wireless adapters.
