...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.
