2018-12-20igb: Fix an issue that PME is not enabled during runtime suspendKai-Heng Feng
I210 ethernet card doesn't wakeup when a cable gets plugged. It's because its PME is not set. Since commit 42eca2302146 ("PCI: Don't touch card regs after runtime suspend D3"), if the PCI state is saved, pci_pm_runtime_suspend() stops calling pci_finish_runtime_suspend(), which enables the PCI PME. To fix the issue, let's not to save PCI states when it's runtime suspend, to let the PCI subsystem enables PME.

2018-12-20ice: Do not enable NAPI on q_vectors that have no ringsYoung Xiao
If ice driver has q_vectors w/ active NAPI that has no rings, then this will result in a divide by zero error. To correct it I am updating the driver code so that we only support NAPI on q_vectors that have 1 or more rings allocated to them.

2018-12-20i40e: define proper net_device::neigh_priv_lenKonstantin Khorenko
Out of bound read reported by KASan. i40iw_net_event() reads unconditionally 16 bytes from neigh->primary_key while the memory allocated for "neighbour" struct is evaluated in neigh_alloc() as tbl->entry_size + dev->neigh_priv_len where "dev" is a net_device.

2018-12-20igb: Change RXPBSIZE size when setting Qav modeJesus Sanchez-Palencia
Section 4.5.9 of the datasheet says that the total size of all packet buffers combined (TxPB 0 + 1 + 2 + 3 + RxPB + BMC2OS + OS2BMC) must not exceed 60KB. Today we are configuring a total of 62KB, so reduce the RxPB from 32KB to 30KB in order to respect that. The choice of changing RxPBSIZE here is mainly because it seems more correct to give more priority to the transmit packet buffers over the receiver ones when running in Qav mode. Also, the BMC2OS and OS2BMC sizes are already too short.

2018-12-20igb: reduce CPU0 latency when updating statisticsJeff Kirsher
This change is based off of the work and suggestion of Jan Jablonsky <jan.jablonsky@thalesgroup.com>. The Watchdog workqueue in igb driver is scheduled every 2s for each network interface. That includes updating a statistics protected by spinlock. Function igb_update_stats in this case will be protected against preemption. According to number of a statistics registers (cca 60), processing this function might cause additional cpu load on CPU0. In case of statistics spinlock may be replaced with mutex, which reduce latency on CPU0.

2018-12-20bnxt_en: Add support for 2nd firmware message channel.Venkat Duvvuru
Earlier, some of the firmware commands (ex: CFA_FLOW_*) which are processed by KONG processor were sent to the CHIMP processor from the host. This approach was taken as there was no direct message channel to KONG. CHIMP in turn used to send them to KONG. Newer firmware supports a new message channel which the host can send messages directly to the KONG processor.
