* driver/net/fm/memac_phy: set NEG bit for external MDIOsShaohui Xie2014-11-141-1/+4
| | | | | | | | | | NEG bit default is '1' for external MDIOs as per FMAN-v3 RM, but on some platforms, e.g. T2080QDS, this bit is '0', which leads to MDIO failure on XAUI PHY, so set this bit definitely to align with the RM.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The keystone_nav driver is general driver intended to be used for working with queue manager and pktdma for different IPs like NETCP, AIF, FFTC, etc. So the it's API shouldn't be named like it works only with one of them, it should be general names. The names with prefix like netcp_* rather do for drivers/net/keystone_net.c driver. So it's good to generalize this driver to be used for different IP's and delete confusion with real NETCP driver. The current netcp_* functions of keystone navigator can be used for other settings of pktdma, not only for NETCP. The API of this driver is used by the keystone_net driver to work with NETCP, so net driver also should be corrected. For convenience collect pkdma configurations in drivers/dma/keystone_nav_cfg.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When testing the FEC driver on a mx6solox we noticed that the TDAR bit gets always cleared prior then the READY bit is cleared in the last BD, which causes FEC packets reception to always fail. As explained by Ye Li: "The TDAR bit is cleared when the descriptors are all out from TX ring, but on mx6solox we noticed that the READY bit is still not cleared right after TDAR. These are two distinct signals, and in IC simulation, we found that TDAR always gets cleared prior than the READY bit of last BD becomes cleared. In mx6solox, we use a later version of FEC IP. It looks like that this intrinsic behaviour of TDAR bit has changed in this newer FEC version." Fix this by polling the READY bit of BD after the TDAR polling, which covers the mx6solox case and does not harm the other SoCs. No performance drop has been noticed with this patch applied when testing TFTP transfers on several boards of different i.mx SoCs.

* | rtl8169: Defer network packet processingThierry Reding2014-09-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When network protocol errors occur (such as a file not being found on a TFTP server), the processing done by the NetReceive() function will end up calling the driver's .halt() implementation. However, after that the device no longer has access to the memory buffers and will cause errors such as this in the rtl_recv() function when trying to hand descriptors back to the device: pci_hose_bus_to_phys: invalid physical address This can be fixed by deferring processing of network packets until the descriptors have been handed back. That way rtl_halt() tearing down network buffers is not going to prevent access to the buffers. Reported-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
