2019-01-08cross-tree: phase out dma_zalloc_coherent()Luis Chamberlain
We already need to zero out memory for dma_alloc_coherent(), as such using dma_zalloc_coherent() is superflous. Phase it out. This change was generated with the following Coccinelle SmPL patch: @ replace_dma_zalloc_coherent @ expression dev, size, data, handle, flags; @@ -dma_zalloc_coherent(dev, size, handle, flags) +dma_alloc_coherent(dev, size, handle, flags) Suggested-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> [hch: re-ran the script on the latest tree] Signed-off-by: Christoph Hellwig <hch@lst.de>
2018-09-12net: ethernet: Use phy_set_max_speed() to limit advertised speedAndrew Lunn
Many Ethernet MAC drivers want to limit the PHY to only advertise a maximum speed of 100Mbs or 1Gbps. Rather than using a mask, make use of the helper function phy_set_max_speed().

Now that applications can use the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and hardware timestamps, the drivers need to be modified to unconditionally call skb_tx_timestamp().

2016-12-10net: ethernet: sxgbe: remove private tx queue lockLino Sanfilippo
The driver uses a private lock for synchronization of the xmit function and the xmit completion handler, but since the NETIF_F_LLTX flag is not set, the xmit function is also called with the xmit_lock held. On the other hand the completion handler uses the reverse locking order by first taking the private lock and (in case that the tx queue had been stopped) then the xmit_lock. Improve the locking by removing the private lock and using only the xmit_lock for synchronization instead. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S.

2016-11-16ptp_clock: Allow for it to be optionalNicolas Pitre
In order to break the hard dependency between the PTP clock subsystem and ethernet drivers capable of being clock providers, this patch provides simple PTP stub functions to allow linkage of those drivers into the kernel even when the PTP subsystem is configured out. Drivers must be ready to accept NULL from ptp_clock_register() in that case. And to make it possible for PTP to be configured out, the select statement in those driver's Kconfig menu entries is converted to the new "imply" statement. This way the PTP subsystem may have Kconfig dependencies of its own, such as POSIX_TIMERS, without having to make those ethernet drivers unavailable if POSIX timers are cconfigured out. And when support for POSIX timers is selected again then the default config option for PTP clock support will automatically be adjusted accordingly. The pch_gbe driver is a bit special as it relies on extra code in drivers/ptp/ptp_pch.c. Therefore we let the make process descend into drivers/ptp/ even if PTP_1588_CLOCK is unselected.

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.

2014-04-01net: sxgbe: sxgbe_mdio_register() frees the busDan Carpenter
