2019-02-06flow_offload: add flow action infrastructurePablo Neira Ayuso5-6/+102
This new infrastructure defines the nic actions that you can perform from existing network drivers. This infrastructure allows us to avoid a direct dependency with the native software TC action representation.

2019-02-06net/mlx5e: support for two independent packet edit actionsPablo Neira Ayuso1-22/+59
This patch adds pedit_headers_action structure to store the result of parsing tc pedit actions. Then, it calls alloc_tc_pedit_action() to populate the mlx5e hardware intermediate representation once all actions have been parsed. This patch comes in preparation for the new flow_action infrastructure, where each packet mangling comes in an separated action, ie. not packed as in tc pedit.

2019-02-06flow_offload: add flow_rule and flow_match structures and use themPablo Neira Ayuso17-1222/+1209
This patch wraps the dissector key and mask - that flower uses to represent the matching side - around the flow_match structure. To avoid a follow up patch that would edit the same LoCs in the drivers, this patch also wraps this new flow match structure around the flow rule object. This new structure will also contain the flow actions in follow up patches. This introduces two new interfaces: bool flow_rule_match_key(rule, dissector_id) that returns true if a given matching key is set on, and: flow_rule_match_XYZ(rule, &match); To fetch the matching side XYZ into the match container structure, to retrieve the key and the mask with one single call.

2019-02-05e1000e: fix cyclic resets at link up with active txKonstantin Khlebnikov1-9/+6
I'm seeing series of e1000e resets (sometimes endless) at system boot if something generates tx traffic at this time.

2019-02-05net: marvell: mvpp2: fix lack of link interruptsRussell King1-7/+14
Sven Auhagen reports that if he changes a SFP+ module for a SFP module on the Macchiatobin Single Shot, the link does not come back up. For Sven, it is as easy as: - Insert a SFP+ module connected, and use ping6 to verify link is up. - Remove SFP+ module - Insert SFP 1000base-X module use ping6 to verify link is up: Link up event did not trigger and the link is down but that doesn't show the problem for me. Locally, this has been reproduced by: - Boot with no modules. - Insert SFP+ module, confirm link is up. - Replace module with 25000base-X module. Confirm link is up. - Set remote end down, link is reported as dropped at both ends. - Set remote end up, link is reported up at remote end, but not local end due to lack of link interrupt. Fix this by setting up both GMAC and XLG interrupts for port 0, but only unmasking the appropriate interrupt according to the current mode set in the mac_config() method. However, only do the mask/unmask dance when we are really changing the link mode to avoid missing any link interrupts.

2019-02-04net: phy: fixed-phy: Drop GPIO from fixed_phy_add()Linus Walleij11-46/+72
All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.

2019-02-04sh_eth: RX checksum offload supportSergei Shtylyov2-2/+59
Add support for the RX checksum offload. This is enabled by default and may be disabled and re-enabled using 'ethtool': # ethtool -K eth0 rx off # ethtool -K eth0 rx on Some Ether MACs provide a simple checksumming scheme which appears to be completely compatible with CHECKSUM_COMPLETE: sum of all packet data after the L2 header is appended to packet data; this may be trivially read by the driver and used to update the skb accordingly. The same checksumming scheme is implemented in the EtherAVB MACs and now supported by the 'ravb' driver. In terms of performance, throughput is close to gigabit line rate with the RX checksum offload both enabled and disabled. The 'perf' output, however, appears to indicate that significantly less time is spent in do_csum() -- this is as expected.

Replace magic numbers with proper constants. The original patch is from Andrew, I extended / adjusted certain parts: - Use decimal bit numbers. The datasheet uses hex bit numbers 0 ..

Shared buffer allocation is usually done in cell increments. Drivers will either round up the allocation or refuse the configuration if it's not an exact multiple of cell size. Drivers know exactly the cell size of shared buffer, so help out users by providing this information in dumps.

2019-02-03socket: Rename SO_RCVTIMEO/ SO_SNDTIMEO with _OLD suffixesDeepa Dinamani8-16/+28
SO_RCVTIMEO and SO_SNDTIMEO socket options use struct timeval as the time format. struct timeval is not y2038 safe. The subsequent patches in the series add support for new socket timeout options with _NEW suffix that will use y2038 safe data structures. Although the existing struct timeval layout is sufficiently wide to represent timeouts, because of the way libc will interpret time_t based on user defined flag, these new flags provide a way of having a structure that is the same for all architectures consistently. Rename the existing options with _OLD suffix forms so that the right option is enabled for userspace applications according to the architecture and time_t definition of libc.

2019-02-03socket: Add struct __kernel_sock_timevalDeepa Dinamani1-0/+5
The new type is meant to be used as a y2038 safe structure to be used as part of cmsg data. Presently the SO_TIMESTAMP socket option uses struct timeval for timestamps. This is not y2038 safe. Subsequent patches in the series add new y2038 safe socket option to be used in the place of SO_TIMESTAMP_OLD. struct __kernel_sock_timeval will be used as the timestamp format at that time. struct __kernel_sock_timeval also maintains the same layout across 32 bit and 64 bit ABIs.

2019-02-03socket: Use old_timeval types for socket timestampsDeepa Dinamani7-12/+12
As part of y2038 solution, all internal uses of struct timeval are replaced by struct __kernel_old_timeval and struct compat_timeval by struct old_timeval32. Make socket timestamps use these new types. This is mainly to be able to verify that the kernel build is y2038 safe when such non y2038 safe types are not supported anymore.
