Not that many users left, lets kill it. TX_LOCKED was meant to be used by LLTX drivers when spin_trylock() failed. Stack then re-queued if collisions happened on different cpus or free'd the skb to prevent deadlocks.
Most of the driver removal patches fall into one of three categories: 1. remove the driver-private tx lock (and LLTX flag), or... 2. convert spin_trylock to plain spin_lock, or... 3. convert TX_LOCKED to free+TX_OK Patches are grouped by these categories, last patch is the actual removal. All driver changes were compile tested only with exception of atl1e.
