net: altera_tse: fix msgdma_tx_completion on non-zero fill_level case

2019-03-23T07:18:56Z

[ Upstream commit 6571ebce112a21ec9be68ef2f53b96fcd41fd81b ] If fill_level was not zero and status was not BUSY, result of "tx_prod - tx_cons - inuse" might be zero. Subtracting 1 unconditionally results invalid negative return value on this case. Make sure not to return an negative value.

net: altera_tse: fix connect_local_phy error path

2019-03-23T07:18:53Z

[ Upstream commit 17b42a20d7ca59377788c6a2409e77569570cc10 ] The connect_local_phy should return NULL (not negative errno) on error, since its caller expects it. Signed-off-by: Atsushi Nemoto Acked-by: Thor Thayer Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

net: eth: altera: fix napi poll_list corruption

2015-10-27T13:33:10Z

[ Upstream commit 4548a697e4969d695047cebd6d9af5e2f6cc728e ] tse_poll() calls __napi_complete() with irq enabled. This leads napi poll_list corruption and may stop all napi drivers working. Use napi_complete() instead of __napi_complete(). Signed-off-by: Atsushi Nemoto Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

Altera TSE: Add support for no PHY

2014-10-06T01:39:40Z

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 Signed-off-by: David S. Miller

Altera TSE: Move PHY get addr and MDIO create

2014-10-06T01:39:40Z

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 Signed-off-by: David S. Miller

net: ethernet: Remove superfluous ether_setup after alloc_etherdev

2014-10-03T22:31:40Z

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.

Conflicts: drivers/net/bonding/bond_alb.c drivers/net/ethernet/altera/altera_msgdma.c drivers/net/ethernet/altera/altera_sgdma.c net/ipv6/xfrm6_output.c Several cases of overlapping changes. The xfrm6_output.c has a bug fix which overlaps the renaming of skb->local_df to skb->ignore_df. In the Altera TSE driver cases, the register access cleanups in net-next overlapped with bug fixes done in net. Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller

Altera TSE: Disable Multicast filtering to workaround problem

2014-05-15T20:46:46Z

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 Signed-off-by: David S. Miller

Altera TSE: Fix sparse errors and warnings

2014-05-15T20:46:46Z

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] *addr altera_tse_ethtool.c:136:19: got unsigned int * ... altera_sgdma.c:129:31: warning: cast removes address space of expression Signed-off-by: Vince Bridgers Signed-off-by: David S.

net: get rid of SET_ETHTOOL_OPS

2014-05-13T21:43:20Z

net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.
