nl80211: add extra-ies only if allowed by driver
Upgrading wpa_supplicant from 2.9 to 2.10 breaks broadcom-wl
based adapters. The reason for it is hostapd tries to install additional
IEs for scanning while the driver does not support this.
The kernel indicates the maximum number of bytes for additional scan IEs
using the NL80211_ATTR_MAX_SCAN_IE_LEN attribute. Save this value and
only add additional scan IEs in case the driver can accommodate these
additional IEs.
