* gianfar: Fix Tx flow control deactivationClaudiu Manoil2017-09-051-1/+1
| | | | | | | | | | | | | | | | The wrong register is checked for the Tx flow control bit, it should have been maccfg1 not maccfg2. This went unnoticed for so long probably because the impact is hardly visible, not to mention the tangled code from adjust_link(). First, link flow control (i.e. handling of Rx/Tx link level pause frames) is disabled by default (needs to be enabled via 'ethtool -A'). Secondly, maccfg2 always returns 0 for tx_flow_oldval (except for a few old boards), which results in Tx flow control remaining always on once activated.

| * fsl/man: Inherit parent device and of_nodeFlorian Fainelli2017-08-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Junote Cai reported that he was not able to get a DSA setup involving the Freescale DPAA/FMAN driver to work and narrowed it down to of_find_net_device_by_node(). This function requires the network device's device reference to be correctly set which is the case here, though we have lost any device_node association there. The problem is that dpaa_eth_add_device() allocates a "dpaa-ethernet" platform device, and later on dpaa_eth_probe() is called but SET_NETDEV_DEV() won't be propagating &pdev->dev.of_node properly. Fix this by inherenting both the parent device and the of_node when dpaa_eth_add_device() creates the platform device.

* | net: fec: Allow reception of frames bigger than 1522 bytesAndrew Lunn2017-07-311-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The FEC Receive Control Register has a 14 bit field indicating the longest frame that may be received. It is being set to 1522. Frames longer than this are discarded, but counted as being in error. When using DSA, frames from the switch has an additional header, either 4 or 8 bytes if a Marvell switch is used. Thus a full MTU frame of 1522 bytes received by the switch on a port becomes 1530 bytes when passed to the host via the FEC interface. Change the maximum receive size to 2048 - 64, where 64 is the maximum rx_alignment applied on the receive buffer for AVB capable FEC cores. Use this value also for the maximum receive buffer size. The driver is already allocating a receive SKB of 2048 bytes, so this change should not have any significant effects. Tested on imx51, imx6, vf610.

| | | | | | | | | | | | | | | | | | Many boards use i2c/spi expander gpio as phy-reset-gpios and these gpios maybe registered after fec port, driver should check the return value of .of_get_named_gpio().

* | dpaa_eth: use AVOIDBLOCK for Tx confirmation queuesMadalin Bucur2017-04-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | The AVOIDBLOCK flag determines the Tx confirmation queues processing to be redirected to any available CPU when the current one is slow in processing them. This may result in a higher Tx confirmation interrupt count but may reduce pressure on a certain CPU that with the previous setting would process all Tx confirmation frames.
