The Kconfig currently controlling compilation of this code is: drivers/net/ethernet/ti/Kconfig:config TI_CPSW_PHY_SEL drivers/net/ethernet/ti/Kconfig: bool "TI CPSW Switch Phy sel Support" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modularity so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments. Cc: "David S.

The Makefile currently controlling compilation of this code lists it under "obj-y" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. We can change to one of the other priority initcalls (subsys?) at any later date, if desired. We can't remove module.h since the file uses other module related stuff even though it is not modular itself. We move the information from the MODULE_LICENSE tag to the top of the file, since that information is not captured anywhere else. The MODULE_ALIAS_NET_PF_PROTO becomes a no-op in the non modular case, so it is removed. Cc: "David S.

In preparation to handling system errors at the mlx5_core level, change the interface of cmd_work_handler to accept a 64 bit argument for the vector. This allows to encode a flag that signifies when the handler is called as a result of a driver logic that wishes to terminate commands that the hardware may not be able to terminate. Such command completions are detected at the handler and proper return status is encoded. To be able to terminate page handler commands, we make sure to set the corresponding bit in the bitmask.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-10-08 This series contains updates to i40e and i40evf only (again). Jesse fixes an issue where the driver was issuing a WARN_ON during ring size changes because the code was cloning the rx_ring struct but not zeroing out the pointers before allocating new memory, so simply zero out the pointers. Also reduced the function call overhead by moving the interrupt enable function by moving it to the header file, which it in turn allows us to inline it. Also does a thorough job of code cleanup to fix spaces after declarations, remove unnecessary braces and breaks, remove another __func__ use and general code tidiness. Mitch adds mover verbose error messages when the number of supported VFs is reported in driver init and it different from the number reported in config space. Updated the VF driver to now detect a reset with the VF_ARQLEN register since the enable bit is cleared when the VF is reset and it stays cleared until the VF driver processes the reset and re-enables the admin queue which is more reliable than using the VFGEN_RSTAT as previously. Neerav adds parsing for CEE DCBx TLVs from the LLDP MIB since there is a need to get the CEE DesiredCfg Tx by firmware and DCB configuration Rx from peer for debug and other application purposes. Carolyn fixes a problem where the PF's Flow Director filter table would have an entry that the hardware was unable to add, when this occurs an invalid entry gets replayed and a valid one is lost. Matt fixes an issue where multiple link up messages can be logged resulting from admin queue link status timing when link properties are changed. Shannon adds the ability to control the period link polling through ethtool to be able to switch it off and on for debugging link issues. Serey explicitly assigns the enum index for each VSI type so that the PF and VF always reference to the same VSI type event if the enum lists are different. ==================== Signed-off-by:

The VF really doesn't care about the QOS handle but it will in the future. Since the VF only uses TC0, send it that handle. On the VF side, save the handle and use it to populate the QOS params when we call into the client interface. Change-ID: I76f41b070baeaa09b19383e9168bc677837e0761 Signed-off-by:

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught with peril. It's entirely too easy to miss a reset because none of the bits are sticky. By the time the VF driver reads the register, the reset may have been processed and cleaned up by the PF driver, leaving the register in the same state that it was before the reset. Instead, detect a reset with the VF_ARQLEN register. When the VF is reset, the enable bit in this register is cleared, and it stays cleared until the VF driver processes the reset and re-enables the admin queue. Because we now deal with multiple registers in the reset and watchdog tasks, rename the rstat_val variable to reg_val. Change-ID: Id1df17045c0992e607da0162d31807f7fc20d199 Signed-off-by:

Ran into an issue where PF's VSI type list was different from VF's, which was resulted in different enum index. The VSI type list can be different depending on what build flag is used for PF and VF. The change is to explicitly assign enum index for each VSI type so that PF and VF always reference to the same VSI type event if the enum lists are different.

There's been some need for controlling the periodic link polling for debugging link issues. This patch enables switching it off and on through an ethtool private flag. The link poll remains on by default, but can be turned off with ethtool --set-priv-flags p261p1 LinkPolling off and later turned back on with ethtool --set-priv-flags p261p1 LinkPolling on To check the current status, use ethtool --show-priv-flags p261p1 Change-ID: I32e4ab654ff3eec90a06cf144899971b82d71c40 Signed-off-by:

This patch addresses an issue where multiple link up messages can be logged resulting from aq link status timing when link properties are changed (fc, speed, etc.); solved by using a single function to handle status printing and adding a mechanism to track whether link state (up or down) has actually changed.

This patch fixes a problem where the PF's fdir filter table would have an entry that the hw was unable to add. This notification happens in the hot path, so instead of trying to fix it then, we note the location in the failure case and delete it during regular fdir subtask callback. Without this patch, a case can occur where an invalid entry gets replayed and a valid one is not. Change-ID: I67831c183b5d0309876de807cc434809b74c9cb7 Signed-off-by:

Under certain circumstances, the device may not have enough resources to enable all of the VFs that it advertises in config space. Although the number of supported VFs is reported upon driver init, it is not obvious when this is different from the number reported in config space. To eliminate this confusion, add an error message explaining the problem. Additionally, move the 'Allocating VFs' message down below the error checks so as to prevent further confusion.

The driver was issuing a WARN_ON during ring size changes because the code was cloning the rx_ring struct but not zeroing out the pointers before allocating new memory. Zero out the pointers in the cloned copy before allocating new memory for them. In this case the code was correctly avoiding memory leaks but still triggering the warning.

Daniel Borkmann says: ==================== BPF/random32 updates BPF update to split the prandom state apart, and to move the *once helpers to the core. For details, please see individual patches. Given the changes and since it's in the tree for quite some time, net-next is a better choice in our opinion. v1 -> v2: - Make DO_ONCE() type-safe, remove the kvec helper. Credits go to Alexei Starovoitov for the __VA_ARGS__ hint, thanks! - Add a comment to the DO_ONCE() helper as suggested by Alexei. - Rework prandom_init_once() helper to the new API. - Keep Alexei's Acked-by on the last patch. ==================== Signed-off-by:
