2016-06-28net: ethernet: sxgbe: use phy_ethtool_{get|set}_link_ksettingsPhilippe Reynes
There are two generics functions phy_ethtool_{get|set}_link_ksettings, so we can use them instead of defining the same code in the driver. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-28net: ethernet: sxgbe: use phydev from struct net_devicePhilippe Reynes
The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phydev in the private structure, and update the driver to use the one contained in struct net_device.

2016-03-27net: sxgbe: fix error paths in sxgbe_platform_probe()Rasmus Villemoes
We need to use post-decrement to ensure that irq_dispose_mapping is also called on priv->rxq[0]->irq_no; moreover, if one of the above for loops failed already at i==0 (so we reach one of these labels with that value of i), we'll enter an essentially infinite loop of out-of-bounds accesses.

2015-02-06net: sxgbe: fix error handling in init_rx_ring()Dan Carpenter
There are a couple bugs with the error handling in this function. 1) If we can't allocate "rx_ring->rx_skbuff" then we should call dma_free_coherent() but we don't. 2) free_rx_ring() frees "rx_ring->rx_skbuff_dma" and "rx_ring->rx_skbuff" so calling it in a loop causes a double free. Also it was a bit confusing how we sometimes freed things before doing the goto. I've cleaned it up so it does error handling in normal kernel style.
