net/mlx5e: Fix error flow in tx reporter diagnose

2019-07-28T06:28:35Z

[ Upstream commit 99d31cbd8953c6929da978bf049ab0f0b4e503d9 ] Fix tx reporter's diagnose callback. Propagate error when failing to gather diagnostics information or failing to print diagnostic data per queue.

net/mlx5e: Fix return value from timeout recover function

[ Upstream commit 39825350ae2a52f8513741b36e42118bd80dd689 ] Fix timeout recover function to return a meaningful return value. When an interrupt was not sent by the FW, return IO error instead of 'true'.

net/mlx5e: Rx, Fix checksum calculation for new hardware

2019-07-28T06:28:35Z

[ Upstream commit db849faa9bef993a1379dc510623f750a72fa7ce ] CQE checksum full mode in new HW, provides a full checksum of rx frame. Covering bytes starting from eth protocol up to last byte in the received frame (frame_size - ETH_HLEN), as expected by the stack. Fixing up skb->csum by the driver is not required in such case. This fix is to avoid wrong checksum calculation in drivers which already support the new hardware with the new checksum mode.

net/mlx5e: Fix port tunnel GRE entropy control

2019-07-28T06:28:35Z

[ Upstream commit 914adbb1bcf89478ac138318d28b302704564d59 ] GRE entropy calculation is a single bit per card, and not per port. Force disable GRE entropy calculation upon the first GRE encap rule, and release the force at the last GRE encap rule removal. This is done per port.

vrf: make sure skb->data contains ip header to make routing

2019-07-28T06:28:33Z

[ Upstream commit 107e47cc80ec37cb332bd41b22b1c7779e22e018 ] vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing using ip/ipv6 addresses, but don't make sure the header is available in skb->data[] (skb_headlen() is less then header size). Case: 1) igb driver from intel. 2) Packet size is greater then 255. 3) MPLS forwards to VRF device. So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound() functions.

sky2: Disable MSI on ASUS P6T

2019-07-28T06:28:32Z

[ Upstream commit a261e3797506bd561700be643fe1a85bf81e9661 ] The onboard sky2 NIC on ASUS P6T WS PRO doesn't work after PM resume due to the infamous IRQ problem. Disabling MSI works around it, so let's add it to the blacklist. Unfortunately the BIOS on the machine doesn't fill the standard DMI_SYS_* entry, so we pick up DMI_BOARD_* entries instead.
