Add ability to load a set of custom KPU entries. This allows for flexible support for custom protocol parsing. AF driver will attempt to load the profile and verify if it can fit hardware capabilities. If not, it will revert to the built-in profile. Next it will replace the first KPU_MAX_CST_LT (2) entries in each KPU in default profile with entries read from the profile image. The built-in profile should always contain KPU_MAX_CSR_LT first no-match entries and AF driver will disable those in the KPU unless custom profile is loaded. Profile file contains also a list of default protocol overrides to allow for custom protocols to be used there. Signed-off-by:

Fix to return -EFAULT from the error handling case instead of 0, as done elsewhere in this function. By the way, when get_zeroed_page() fails, directly return -ENOMEM to simplify code. Fixes: 2c69448b ("ehea: DLPAR memory add fix") Reported-by:

stmmac_mdio_register() has logic to search for PHYs on the MDIO bus and assign them IRQ lines, as well as to set priv->plat->phy_addr. If no PHY is found, the "found" variable remains set to 0 and the function errors out. After the introduction of commit f213bbe8 ("net: stmmac: Integrate it with DesignWare XPCS"), the "found" variable was immediately reused for searching for a PCS on the same MDIO bus. This can result in 2 types of potential problems (none of them seems to be seen on the only Intel system that sets has_xpcs = true, otherwise it would have been reported): 1. If a PCS is found but a PHY is not, then the code happily exits with no error. One might say "yes, but this is not possible, because of_mdiobus_register will probe a PHY for all MDIO addresses, including for the XPCS, so if an XPCS exists, then a PHY certainly exists too". Well, that is not true, see intel_mgbe_common_data(): /* Ensure mdio bus scan skips intel serdes and pcs-xpcs */ plat->mdio_bus_data->phy_mask = 1 << INTEL_MGBE_ADHOC_ADDR; plat->mdio_bus_data->phy_mask |= 1 << INTEL_MGBE_XPCS_ADDR; 2. A PHY is found but an MDIO device with the XPCS PHY ID isn't, and in that case, the error message will be "No PHY found". Confusing. Signed-off-by:

Mat Martineau says: ==================== mptcp: Miscellaneous cleanup Here are some cleanup patches we've collected in the MPTCP tree. Patches 1-4 do some general tidying. Patch 5 adds an explicit check at netlink command parsing time to require a port number when the 'signal' flag is set, to catch the error earlier. Patches 6 & 7 fix up the MPTCP 'enabled' sysctl, enforcing it as a boolean value, and ensuring that the !CONFIG_SYSCTL build still works after the boolean change. ==================== Link: https://lore.kernel.org/r/20210527235430.183465-1-mathew.j.martineau@linux.intel.comSigned-off-by:

To avoid confusions, it seems better to parse this sysctl parameter as a boolean. We use it as a boolean, no need to parse an integer and bring confusions if we see a value different from 0 and 1, especially with this parameter name: enabled. It seems fine to do this modification because the default value is 1 (enabled). Then the only other interesting value to set is 0 (disabled). All other values would not have changed the default behaviour. Suggested-by:

Since the introduction of the sysctl support in MPTCP with commit 784325e9 ("mptcp: new sysctl to control the activation per NS"), we don't check CONFIG_SYSCTL. Until now, that was not an issue: the register and unregister functions were replaced by NO-OP one if SYSCTL was not enabled in the config. The only thing we could have avoid is not to reserve memory for the table but that's for the moment only a small table per net-ns. But the following commit is going to use SYSCTL_ZERO and SYSCTL_ONE which are not be defined if SYSCTL is not enabled in the config. This causes 'undefined reference' errors from the linker.

More RX/TX queues on a network card help spread the CPU load among cores and achieve higher overall networking performance. The new Mikrotik 10/25G NIC supports 4 RX and 4 TX queues. TX queues are treated with equal priority. RX queue balancing is fixed based on L2/L3/L4 hash. This adds support for 4 RX/TX queues while maintaining backwards compatibility with older hardware. Simultaneous TX + RX performance on AMD Threadripper 3960X with Mikrotik 10/25G NIC improved from 1.6Mpps to 3.2Mpps per port. Backwards compatiblitiy was verified with AR8151 and AR8131 based NICs.
