NAME
       ieee80211_alloc_hw - Allocate a new hardware device

SYNOPSIS
       struct ieee80211_hw * ieee80211_alloc_hw(size_t priv_data_len, const struct ieee80211_ops * ops);

ARGUMENTS
       priv_data_len
	   length of private data

       ops
	   callbacks for this device

DESCRIPTION
       This must be called once for each hardware device. The returned pointer must be used to refer to this device when calling other functions.
       mac80211 allocates a private data area for the driver pointed to by priv in struct ieee80211_hw, the size of this area is given as
