Subject: [PATCH net v2 0/4] net: ll_temac: Bugfixes

Fix a number of bugs which have been present since the first commit.

The bugs fixed in patch 1,2 and 4 have all been observed in real systems, and
was relatively easy to reproduce given an appropriate stress setup.

Changes since v1:

- Changed error handling of of dma_map_single() in temac_start_xmit() to drop
  packet instead of returning NETDEV_TX_BUSY.

Esben Haabendal (4):
  net: ll_temac: Fix race condition causing TX hang
  net: ll_temac: Add more error handling of dma_map_single() calls
  net: ll_temac: Fix RX buffer descriptor handling on GFP_ATOMIC
    pressure
  net: ll_temac: Handle DMA halt condition caused by buffer underrun
