2018-06-28net: phy: xgmiitorgmii: Check phy_driver ready before accessingBrandon Maier1-0/+5
Since a phy_device is added to the global mdio_bus list during phy_device_register(), but a phy_device's phy_driver doesn't get attached until phy_probe(). It's possible of_phy_find_device() in xgmiitorgmii will return a valid phy with a NULL phy_driver. Leading to a NULL pointer access during the memcpy().

2018-06-26net: sched: call reoffload op on block callback regJohn Hurley1-2/+2
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).

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.

2018-06-24qmi_wwan: add support for the Dell Wireless 5821e moduleAleksander Morgado1-0/+1
This module exposes two USB configurations: a QMI+AT capable setup on USB config #1 and a MBIM capable setup on USB config #2. By default the kernel will choose the MBIM capable configuration as long as the cdc_mbim driver is available. This patch adds support for the QMI port in the secondary configuration.

2018-06-23r8169: enable ASPM on RTL8168E-VLHeiner Kallweit1-0/+2
Let's enable ASPM also on the RTL8168E-VL (chip version 34). Works fine on my Zotac Mini PC with this chip. Temperature when being idle is significantly lower than before due to reaching deeper PC states. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

2018-06-23r8169: align ASPM entry latency setting with vendor driverHeiner Kallweit1-24/+19
The r8168 vendor driver always uses value 0x27. In r8169 we have few chips where 0x17 is used. So far this didn't matter because ASPM was disabled anyway. Now that ASPM was re-enabled let's also use 0x27 only. One of the chips affected by this change is RTL8168E-VL, on my system with this chip value 0x27 works fine. In addition rename rtl_csi_access_enable_2() to rtl_set_def_aspm_entry_latency() to make clear that we set the default ASPM entry latency.

2018-06-23net: pch_gbe: Clean up pch_gbe_set_multiPaul Burton1-17/+16
Refactor pch_gbe_set_multi in order to avoid unnecessary indentation & make it clearer what the code is doing. 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 Burton1-54/+19
The pch_gbe driver sets up multicast address filters using a convoluted mechanism by which pch_gbe_set_multi allocates an array to hold multicast addresses, copies desired addresses into that array, calls a pch_gbe_mac_mc_addr_list_update function which copies addresses out of that array into MAC registers, then frees the array. 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.
