Alternatively #include <linux/ieee80211.h>, and avoid the WE header/constants? Or would you expect WE helpers in this file as well?

IEEE80211_SSID_MAX_LEN
Also, are we worried about drivers interrupting each other and getting the others SSID? In which case maybe something like print_mac:
/* in lib80211.h */
#define DECLARE_SSID_BUF(x) char x[IEEE80211_SSID_MAX_LEN * 2 + 1]
const char *print_ssid(char *escaped, const char *ssid, u8 ssid_len);

Dave.
