2014-10-05Altera TSE: Add support for no PHYWalter Lozano1-0/+8
This patch avoids PHY and MDIO probing if no PHY chip is present. This is the case mainly in optical links where there is no need for PHY chip, and therefore no need of MDIO. In this scenario Ethernet MAC is directly connected to an optical module through an external SFP transceiver. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S.

2014-10-05Altera TSE: Move PHY get addr and MDIO createWalter Lozano1-21/+36
Move PHY get addr and MDIO create to a new function to improve readability and make it easier to avoid its usage. This will be useful for example in the case where there is no PHY chip. Signed-off-by: Walter Lozano <walter@vanguardiasur.com.ar> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-10-03net: ethernet: Remove superfluous ether_setup after alloc_etherdevTobias Klauser1-1/+0
There is no need to call ether_setup after alloc_ethdev since it was already called there. Follow commits c706471b2601 ("net: axienet: remove unnecessary ether_setup after alloc_etherdev") and 3c87dcbfb36c ("net: ll_temac: Remove unnecessary ether_setup after alloc_etherdev") and fix the pattern in all remaining ethernet drivers.

2014-05-15Altera TSE: Disable Multicast filtering to workaround problemVince Bridgers1-0/+5
This patch disables multicast hash filtering if present in the hardware and uses promiscuous mode instead until the problem with multicast filtering has been debugged, integrated and tested. Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-15Altera TSE: Fix sparse errors and warningsVince Bridgers1-57/+71
This patch fixes the many sparse errors and warnings contained in the initial submission of the Altera Triple Speed Ethernet driver, and a few minor cppcheck warnings. Changes are tested on ARM and NIOS2 example designs, and compile tested against multiple architectures. Typical issues addressed were as follows: altera_tse_ethtool.c:136:19: warning: incorrect type in argument 1 (different address spaces) altera_tse_ethtool.c:136:19: expected void const volatile [noderef] <asn:2>*addr altera_tse_ethtool.c:136:19: got unsigned int *<noident> ... altera_sgdma.c:129:31: warning: cast removes address space of expression Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-04-26Altera TSE: Fix Panic in probe routine when phy probe failsVince Bridgers1-21/+24
This patch addresses a fault in the error recovery path of the probe routine where the netdev structure was not being unregistered properly leading to a panic only when the phy probe failed. Abbreviated panic stack seen is as follows: (free_netdev+0xXX) from (altera_tse_probe+0xXX) (altera_tse_probe+0xXX) from (platform_drv_probe+0xXX) (platform_drv_probe+0xXX) from (driver_probe_device+0xXX) (driver_probe_device+0xXX) from (__driver_attach+0xXX) (__driver_attach+0xXX) from (bus_for_each_dev+0xXX) (bus_for_each_dev+0xXX) from (driver_attach+0xXX) (driver_attach+0xXX) from (bus_add_driver+0xXX) (bus_add_driver+0xXX) from (driver_register+0xXX) (driver_register+0xXX) from (__platform_driver_register+0xXX) (__platform_driver_register+0xXX) from (altera_tse_driver_init+0xXX) (altera_tse_driver_init+0xXX) from (do_one_initcall+0xXX) (do_one_initcall+0xXX) from (kernel_init_freeable+0xXX) (kernel_init_freeable+0xXX) from (kernel_init+0xXX) (kernel_init+0xXX) from (ret_from_fork+0xXX) Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S.

2014-04-26Altera TSE: Work around unaligned DMA receive packet issue with Altera SGDMAVince Bridgers1-10/+20
This patch works around a recently discovered unaligned receive dma problem with the Altera SGMDA. The Altera SGDMA component cannot be configured to DMA data to unaligned addresses for receive packet operations from the Triple Speed Ethernet component because of a potential data transfer corruption that can occur. This patch addresses this issue by utilizing the shift 16 bits feature of the Altera Triple Speed Ethernet component and modifying the receive buffer physical addresses accordingly such that the target receive DMA address is always aligned on a 32-bit boundary.
