Regression in 2.6.27-git from commit 43ac2ca3840f64

On my x86_64 system, the mainline 2.6.27-git kernel (v2.6.27-6030-g6da0b38)
shows the following anomaly with the 'iwlist scan' command:

          Cell 03 - Address: 00:14:BF:85:49:FA

This problem was bisected to commit 43ac2ca3840f64f699a239535c590fa7ebaaac27,
entitled "mac80211: Handle scan result IEs in one block". The same bug is
present in the wireless-testing tree.
