Currently packets with non-hardware-accelerated vlan cannot be handled by GRO. This causes low performance for 802.1ad and stacked vlan, as their vlan tags are currently not stripped by hardware.

This Directly associates the sampled packet with the path it takes through the virtual switch. Path information currently includes mangling, encapsulation and decapsulation actions for tunneling protocols GRE, VXLAN, Geneve, MPLS and QinQ, but this extension requires no further changes to accommodate datapath actions that may be added in the future.

When we scan a packet for GRO processing, we want to see the most common packet types in the front of the offload_base list. So add a priority field so we can handle this properly. IPv4/IPv6 get the highest priority with the implicit zero priority field. Next comes ethernet with a priority of 10, and then we have the MPLS types with a priority of 15.

Linux 3.17 and earlier are explicitly engineered so that if the app doesn't specifically request a CC module on a listener before the SYN arrives, then the child gets the system default CC when the connection is established. See tcp_init_congestion_control() in 3.17 or earlier, which says "if no choice made yet assign the current value set as default". The change ("net: tcp: assign tcp cong_ops when tcp sk is created") altered these semantics, so that children got their parent listener's congestion control even if the system default had changed after the listener was created. This commit returns to those original semantics from 3.17 and earlier, since they are the original semantics from 2007 in 4d4d3d1e ("[TCP]: Congestion control initialization."), and some Linux congestion control workflows depend on that. In summary, if a listener socket specifically sets TCP_CONGESTION to "x", or the route locks the CC module to "x", then the child gets "x". Otherwise the child gets current system default from net.ipv4.tcp_congestion_control. That's the behavior in 3.17 and earlier, and this commit restores that.

Normally the program attachment place (like sockets, qdiscs) takes care of rcu protection and calls bpf_prog_put() after a grace period. The programs stored inside prog_array may not be attached anywhere, so prog_array needs to take care of preserving rcu protection. Otherwise bpf_tail_call() will race with bpf_prog_put(). To solve that introduce bpf_prog_put_rcu() helper function and use it in 3 places where unattached program can decrement refcnt: closing program fd, deleting/replacing program in prog_array.

Previously, mlx4_en allocated EQs and used them exclusively. This affected RoCE performance, as applications which are events sensitive were limited to use only the legacy EQs. Change that by introducing an EQ pool. This pool is managed by mlx4_core. EQs are assigned to ports (when there are limited number of EQs, multiple ports could be assigned to the same EQs). An exception to this rule is the ASYNC EQ which handles various events. Legacy EQs are completely removed as all EQs could be shared. When a consumer (mlx4_ib/mlx4_en) requests an EQ, it asks for EQ serving on a specific port. The core driver calculates which EQ should be assigned to that request. Because IRQs are shared between IB and Ethernet modules, their names only include the PCI device BDF address.

This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected.

XFS uses non-stanard batch sizes for avoiding frequent global counter updates on it's allocated inode counters, as they increment or decrement in batches of 64 inodes. Hence the standard percpu counter batch of 32 means that the counter is effectively a global counter. Currently Xfs uses a batch size of 128 so that it doesn't take the global lock on every single modification. However, Xfs also needs to compare accurately against zero, which means we need to use percpu_counter_compare(), and that has a hard-coded batch size of 32, and hence will spuriously fail to detect when it is supposed to use precise comparisons and hence the accounting goes wrong. Add __percpu_counter_compare() to take a custom batch size so we can use it sanely in XFS and factor percpu_counter_compare() to use it.

da91309e (cpumask: Utility function to set n'th cpu...) created a genuinely weird function. I never saw it before, it went through DaveM. (He only does this to make us other maintainers feel better about our own mistakes.) cpumask_set_cpu_local_first's purpose is say "I need to spread things across N online cpus, choose the ones on this numa node first"; you call it in a loop. It can fail. One of the two callers ignores this, the other aborts and fails the device open. It can fail in two ways: allocating the off-stack cpumask, or through a convoluted codepath which AFAICT can only occur if cpu_online_mask changes. Which shouldn't happen, because if cpu_online_mask can change while you call this, it could return a now-offline cpu anyway. It contains a nonsensical test "!cpumask_of_node(numa_node)". This was drawn to my attention by Geert, who said this causes a warning on Sparc. It sets a single bit in a cpumask instead of returning a cpu number, because that's what the callers want. It could be made more efficient by passing the previous cpu rather than an index, but that would be more invasive to the callers.

After commit 07f4c900 ("tcp/dccp: try to not exhaust ip_local_port_range in connect()") it is advised to have an even number of ports described in /proc/sys/net/ipv4/ip_local_port_range This means start/end values should have a different parity.
