net: ethernet: litex: Fix return type of liteeth_start_xmit

2022-09-20T01:23:39Z

The ndo_start_xmit field in net_device_ops is expected to be of type netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev). The mismatched return type breaks forward edge kCFI since the underlying function definition does not match the function hook definition. The return type of liteeth_start_xmit should be changed from int to netdev_tx_t.

net: ethernet: litex: Add the dependency on HAS_IOMEM

2022-02-09T04:43:40Z

The LiteX driver uses devm io function API which needs HAS_IOMEM enabled, so add the dependency on HAS_IOMEM.

litex_liteeth: Fix a double free in the remove function

2021-11-07T21:51:17Z

'netdev' is a managed resource allocated in the probe using 'devm_alloc_etherdev()'. It must not be freed explicitly in the remove function. Fixes: ee7da21ac4c3 ("net: Add driver for LiteX's LiteETH network interface") Signed-off-by: Christophe JAILLET Signed-off-by: David S. Miller

net: ethernet: litex: Remove unnecessary print function dev_err()

2021-11-05T10:16:12Z

net: Add driver for LiteX's LiteETH network interface

2021-08-26T11:13:52Z

LiteX is a soft system-on-chip that targets FPGAs. LiteETH is a basic network device that is commonly used in LiteX designs. The driver was first written in 2017 and has been maintained by the LiteX community in various trees. Thank you to all who have contributed.
