Subject: [PATCH net-next 0/6] net: core: remove TX_LOCKED support

 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.
