2018-06-27nfp: bpf: allow source ptr type be map ptr in memcpy optimizationJiong Wang
Map read has been supported on NFP, this patch enables optimization for memcpy from map to packet. This patch also fixed one latent bug which will cause copying from unexpected address once memcpy for map pointer enabled. The fixed code path was not exercised before.

2018-06-26mdio-mux-gpio: Remove VLA usageKees Cook
In the quest to remove all stack VLA usage from the kernel[1], this allocates the values buffer during the callback instead of putting it on the stack.

2018-06-26net: sched: call reoffload op on block callback regJohn Hurley
Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active).

2018-06-26mlxsw: spectrum_switchdev: Ban PVID change if bridge has a RIFPetr Machata
When traffic passes through a router port, it needs to be assigned a FID for ASIC to forward correctly. For bridges, this FID used to be the one corresponding to VLAN 1.

Manage pending per-NAPI GRO packets via list_head. Return an SKB pointer from the GRO receive handlers. When GRO receive handlers return non-NULL, it means that this SKB needs to be completed at this time and removed from the NAPI queue. Several operations are greatly simplified by this transformation, especially timing out the oldest SKB in the list when gro_count exceeds MAX_GRO_SKBS, and napi_gro_flush() which walks the queue in reverse order.

The one behavioral change from this patch is that we'll no longer configure the MAC address registers for multicast addresses when the IFF_PROMISC or IFF_ALLMULTI flags are set. In these cases, just as when we want to monitor more multicast addresses than we have MAC address registers, we disable multicast filtering so the MAC address registers are unused.

2018-06-23net: pch_gbe: Inline pch_gbe_mac_mc_addr_list_updatePaul Burton

This patch simplifies this somewhat by inlining pch_gbe_mac_mc_addr_list_update into pch_gbe_set_multi, and removing the requirement for the MAC addresses to stored consecutively in a single array.

2018-06-23net: pch_gbe: Remove PCH_GBE_MAC_IFOP_RGMII definePaul Burton
The pch_gbe driver currently presumes that the PHY is connected using RGMII, and would need further work to support other buses. It includes a define which is always set that conditionalises some of the RGMII-specific code regardless. Remove it. If we do ever support different MII buses then preprocessor defines won't be the best way to select between them anyway. Signed-off-by: Paul Burton <paul.burton@mips.com> Signed-off-by: David S.

2018-06-23net: pch_gbe: Remove pch_gbe_hal_setup_init_funcsPaul Burton
The pch_gbe driver calls a pch_gbe_hal_setup_init_funcs function which ultimately sets the value of one field in struct pch_gbe_phy_info in a convoluted way. This patch removes pch_gbe_hal_setup_init_funcs in favor of inlining it, and in turn its callee pch_gbe_plat_init_function_pointers, into the single caller pch_gbe_sw_init. With this pch_gbe_api.c & pch_gbe_api.h are essentially empty, so they are removed & inclusions of the latter replaced with pch_gbe_phy.h which was previously being included via pch_gbe_api.h.

2018-06-23net: pch_gbe: Remove get_bus_info HAL abstractionPaul Burton
For some reason the pch_gbe driver contains a struct pch_gbe_functions with pointers used by a HAL abstraction layer, even though there is only one implementation of each function. This patch removes the get_bus_info abstraction. Its single implementation (pch_gbe_plat_get_bus_info) only sets values within a struct pch_gbe_bus_info which is never used, so we simply remove the call to it in pch_gbe_probe & remove struct pch_gbe_bus_info entirely. Now that struct pch_gbe_functions is empty we remove it entirely too. Signed-off-by: Paul Burton <paul.burton@mips.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch removes the init_hw abstraction in favor of inlining its single implementation (pch_gbe_plat_init_hw) into its single caller (pch_gbe_reset).

For some reason the pch_gbe driver contains a struct pch_gbe_functions with pointers used by a HAL abstraction layer, even though there is only one implementation of each function. This patch removes the read_phy_reg & write_phy_reg abstractions in favor of calling pch_gbe_phy_read_reg_miic & pch_gbe_phy_write_reg_miic directly.
