Currently, ie_len in cfg80211_notify_new_peer_candidate is defined as
1-byte field, capping the maximum IE list size at 255 bytes. When a
large beacon is received, the IE list is truncated, passing incomplete
data to wpa_supplicant. This causes supplicant to fail parsing the IEs.

Increasing the size of ie_len to allow the full length of the IE list to
be forwarded properly.

* [PATCH] wifi: nl80211: Increase ie_len size to prevent truncated IEs in new peer notifications

Currently, ie_len in cfg80211_notify_new_peer_candidate is defined as
1-byte field, capping the maximum IE list size at 255 bytes. When a
large beacon is received, the IE list is truncated, passing incomplete
data to wpa_supplicant. This causes supplicant to fail parsing the IEs.

Increasing the size of ie_len to allow the full length of the IE list to
be forwarded properly.
