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

[Sascha Hauer <s.hauer@pengutronix.de>]

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
  net: ks8851_mll: do not read past the receive buffer
  net: liteeth: do not read past the receive buffer
  net: liteeth: do not set len to 0 before printing it
  net: smc911x: Fix amount of words read from RX FIFO
  net: smc911x: do not read past the receive buffer
  net: ks8851_mll: drop return value from ks8851_rx_frame()
  net: let net rx hook return void
