2017-06-08net: propagate tc filter chain index down the ndo_setup_tc callJiri Pirko
We need to push the chain index down to the drivers, so they have the information to which chain the rule belongs. For now, no driver supports multichain offload, so only chain 0 is supported. This is needed to prevent chain squashes during offload for now. Later this will be used to implement multichain offload. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

Some PHY require to wait for a bit after the reset GPIO has been toggled. This adds support for the DT property `phy-reset-post-delay` which gives the delay in milliseconds to wait after reset. If the DT property is not given, no delay is observed. Post reset delay greater than 1000ms are invalid.

There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

2017-03-15mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.Amritha Nambiar
The configurable priority to traffic class mapping and the user specified queue ranges are used to configure the traffic class, overriding the hardware defaults when the 'hw' option is set to 0. However, when the 'hw' option is non-zero, the hardware QOS defaults are used. This patch makes it so that we can pass the data the user provided to ndo_setup_tc. This allows us to pull in the queue configuration if the user requested it as well as any additional hardware offload type requested by using a value other than 1 for the hw value. Finally it also provides a means for the device driver to return the level supported for the offload type via the qopt->hw value. Previously we were just always assuming the value to be 1, in the future values beyond just 1 may be supported.

In addition, the priority of the Rx, Error and Conf queues is lowered but their order is maintained. By default, only one traffic class is enabled, only the low priority Tx queues are used and only the corresponding netdev queues are advertised.

2017-01-30gianfar: synchronize DMA API usage by free_skb_rx_queue w/ gfar_new_pageArseny Solokha
In spite of switching to paged allocation of Rx buffers, the driver still called dma_unmap_single() in the Rx queues tear-down path. The DMA region unmapping code in free_skb_rx_queue() basically predates the introduction of paged allocation to the driver. While being refactored, it apparently hasn't reflected the change in the DMA API usage by its counterpart gfar_new_page(). As a result, setting an interface to the DOWN state now yields the following: # ip link set eth2 down fsl-gianfar ffe24000.ethernet: DMA-API: device driver frees DMA memory with wrong function [device address=0x000000001ecd0000] [size=40] ------------[ cut here ]------------ WARNING: CPU: 1 PID: 189 at lib/dma-debug.c:1123 check_unmap+0x8e0/0xa28 CPU: 1 PID: 189 Comm: ip Tainted: G O 4.9.5 #1 task: dee73400 task.stack: dede2000 NIP: c02101e8 LR: c02101e8 CTR: c0260d74 REGS: dede3bb0 TRAP: 0700 Tainted: G O (4.9.5) MSR: 00021000 <CE,ME> CR: 28002222 XER: 00000000 GPR00: c02101e8 dede3c60 dee73400 000000b6 dfbd033c dfbd36c4 1f622000 dede2000 GPR08: 00000007 c05b1634 1f622000 00000000 22002484 100a9904 00000000 00000000 GPR16: 00000000 db4c849c 00000002 db4c8480 00000001 df142240 db4c84bc 00000000 GPR24: c0706148 c0700000 00029000 c07552e8 c07323b4 dede3cb8 c07605e0 db535540 NIP [c02101e8] check_unmap+0x8e0/0xa28 LR [c02101e8] check_unmap+0x8e0/0xa28 Call Trace: [dede3c60] [c02101e8] check_unmap+0x8e0/0xa28 (unreliable) [dede3cb0] [c02103b8] debug_dma_unmap_page+0x88/0x9c [dede3d30] [c02dffbc] free_skb_resources+0x2c4/0x404 [dede3d80] [c02e39b4] gfar_close+0x24/0xc8 [dede3da0] [c0361550] __dev_close_many+0xa0/0xf8 [dede3dd0] [c03616f0] __dev_close+0x2c/0x4c [dede3df0] [c036b1b8] __dev_change_flags+0xa0/0x174 [dede3e10] [c036b2ac] dev_change_flags+0x20/0x60 [dede3e30] [c03e130c] devinet_ioctl+0x540/0x824 [dede3e90] [c0347dcc] sock_ioctl+0x134/0x298 [dede3eb0] [c0111814] do_vfs_ioctl+0xac/0x854 [dede3f20] [c0111ffc] SyS_ioctl+0x40/0x74 [dede3f40] [c000f290] ret_from_syscall+0x0/0x3c --- interrupt: c01 at 0xff45da0 LR = 0xff45cd0 Instruction dump: 811d001c 7c66482e 813d0020 9061000c 807f000c 5463103a 7cc6182e 3c60c052 386309ac 90c10008 4cc63182 4826b845 <0fe00000> 4bfffa60 3c80c052 388402c4 ---[ end trace 695ae6d7ac1d0c47 ]--- Mapped at: [<c02e22a8>] gfar_alloc_rx_buffs+0x178/0x248 [<c02e3ef0>] startup_gfar+0x368/0x570 [<c036aeb4>] __dev_open+0xdc/0x150 [<c036b1b8>] __dev_change_flags+0xa0/0x174 [<c036b2ac>] dev_change_flags+0x20/0x60 Even though the issue was discovered in 4.9 kernel, the code in question is identical in the current net and net-next trees.
