[PATCH v3 0/9] net: do not read past receive buffer

Several network drivers read overlong packets without checking if the
buffer they read into is large enough. Discard the packets instead
of writing past the buffer.

Changes since v2:
- Add patch to fix amount of words read from RX FIFO
- Fix wrong len printing in liteeth
- Fix wrong too long packet check in smc911x

Changes since v1:
- Do not call net_receive() when we decided to discard a packet
- Add patch to let network device receive hook return void

Sascha Hauer (9):
  net: cs8900: simplify buffer read loop
  net: cs8900: do not read past the receive buffer
