2021-11-22net/ice: Add support for enable_iwarp and enable_roce devlink paramShiraz Saleem6-5/+166
Allow support for 'enable_iwarp' and 'enable_roce' devlink params to turn on/off iWARP or RoCE protocol support for E800 devices. For example, a user can turn on iWARP functionality with, devlink dev param set pci/0000:07:00.0 name enable_iwarp value true cmode runtime This add an iWARP auxiliary rdma device, ice.iwarp.<>, under this PF. A user request to enable both iWARP and RoCE under the same PF is rejected since this device does not support both protocols simultaneously on the same port.

2021-11-22Merge branch 'qca8k-next'David S. Miller2-193/+349
Ansuel Smith says: ==================== Multiple cleanup and feature for qca8k This is a reduced version of the old massive series. Refer to the changelog to know what is removed from this. We clean and convert the driver to GENMASK FIELD_PREP to clean multiple use of various naming scheme. (example we have a mix of _MASK, _S _M, and various name) The idea is to ""simplify"" and remove some shift and data handling by using FIELD API. The patch contains various checkpatch warning and are ignored to not create more mess in the header file. (fixing the too long line warning would results in regs definition less readable) We conver the driver to regmap API as ipq40xx SoC is based on the same reg structure and we need to generilize the read/write access to split the driver to commond and specific code. The conversion to regmap is NOT done for the read/write/rmw operation, the function are reworked to use the regmap helper instead. This is done to keep the patch delta low but will come sooner or later when the code will be split. Any new feature will directly use the regmap helper and the reg set/clear and the busy wait function are migrated to regmap helper as the use of these function is low. We also add a minor patch for MIB counter as qca8337 is missing 2 extra counter, support for mdb and ageing settings. v3: - Try to reduce regmap conversion patch v2: - Move regmap init to sw_probe instead of moving switch id check. - Removed LAGs, mirror extra features will come later in another smaller series. - Squash 2 ageing patch - Add more description about the regmap patch - Rework mdb patch to do operation under the same lock ==================== Signed-off-by: David S.

Add support for mdb add/del function. The ARL table is used to insert the rule. The rule will be searched, deleted and reinserted with the port mask updated. The function will check if the rule has to be updated or insert directly with no deletion of the old rule. If every port is removed from the port mask, the rule is removed. The rule is set STATIC in the ARL table (aka it doesn't age) to not be flushed by fast age function.

2021-11-22net: dsa: qca8k: initial conversion to regmap helperAnsuel Smith1-60/+47
Convert any qca8k set/clear/pool to regmap helper and add missing config to regmap_config struct. Read/write/rmw operation are reworked to use the regmap helper internally to keep the delta of this patch low. These additional function will then be dropped when the code split will be proposed. Ipq40xx SoC have the internal switch based on the qca8k regmap but use mmio for read/write/rmw operation instead of mdio. In preparation for the support of this internal switch, convert the driver to regmap API to later split the driver to common and specific code. The overhead introduced by the use of regamp API is marginal as the internal mdio will bypass it by using its direct access and regmap will be used only by configuration functions or fdb access.

This patch set brings in a common debugfs base directory i.e. /sys/kernel/debugfs/wwan/ in WWAN Subsystem for a WWAN device instance. So that it avoids driver polluting debugfs root with unrelated directories & possible name collusion. Having a common debugfs base directory for WWAN drivers eases user to match control devices with debugfs entries. WWAN Subsystem creates dentry (/sys/kernel/debugfs/wwan) on module load & removes dentry on module unload. When driver registers a new wwan device, dentry (wwanX) is created for WWAN device instance & on driver unregister dentry is removed. New API is introduced to return the wwan device instance dentry so that driver can create debugfs entries under it.

Some devices expose memory-mapped c22-compliant PHYs. Because these devices do not have an MDIO bus, we cannot use the existing helpers. Refactor the existing helpers to allow supplying the values for c22 registers directly, instead of using MDIO to access them. Only get_state and set_advertisement are converted, since they contain the most complex logic. Because set_advertisement is never actually used outside phylink_mii_c22_pcs_config, move the MDIO-writing part into that function. Because some modes do not need the advertisement register set at all, we use -EINVAL for this purpose. Additionally, a new function phylink_pcs_enable_an is provided to determine whether to enable autonegotiation.

It adds a queue based tx shared bounce buffer to memcpy the small packet when the len of xmitted skb is below tx_copybreak(value to distinguish small size and normal size), and reduce the overhead of dma map and unmap when IOMMU is on. Support setting it via ethtool --set-tunable parameter and getting it via ethtool --get-tunable parameter.

Mat Martineau says: ==================== mptcp: More socket option support These patches add MPTCP socket support for a few additional socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT, IPV6_FREEBIND, and IPV6_TRANSPARENT. Patch 1 exposes __ip_sock_set_tos() for use in patch 2. Patch 2 adds IP_TOS support. Patches 3 and 4 add the freebind and transparent support, with a selftest for the latter. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2021-11-20selftests: mptcp: add tproxy test caseFlorian Westphal3-3/+136
No hard dependencies here, just skip if test environ lacks nft binary or the needed kernel config options. The test case spawns listener in ns2 but ns1 will connect to the ip address of ns4. policy routing + tproxy rule will redirect packets to ns2 instead of forward. v3: - update mptcp/config (Mat Martineau) - more verbose SKIP messages in mptcp_connect.sh Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

2021-11-20mptcp: Support for IP_TOS for MPTCP setsockopt()Poorva Sonparote1-0/+40
SOL_IP provides a way to configure network layer attributes in a socket. This patch adds support for IP_TOS for setsockopt(.. ,SOL_IP, ..) Support for SOL_IP is added in mptcp_setsockopt() and IP_TOS is handled in a private function. The idea here is to take in the value passed for IP_TOS and set it to the current subflow, open subflows as well new subflows that might be created after the initial call to setsockopt(). This sync is done using sync_socket_options(.., ssk) and setting the value of tos using __ip_sock_set_tos(ssk,..). The patch has been tested using the packetdrill script here - https://github.com/multipath-tcp/mptcp_net-next/issues/220#issuecomment-947863717 Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/220 Signed-off-by: Poorva Sonparote <psonparo@redhat.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

Making the static function __ip_sock_set_tos() from net/ipv4/ip_sockglue.c accessible by declaring it in include/net/ip.h The reason for doing this is to use this function to set IP_TOS value in mptcp_setsockopt() without the lock.
