Commit 4904b6ea ("net: phy: phylink: Use PHY device interface if N/A") introduced handling for the phy interface mode where this is not known at phylink creation time. This was never added to the OF/fwnode paths, but is necessary when the phy is present in DT, but the phy-mode is not specified. Add this handling. Signed-off-by:

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. Signed-off-by:

dev->gso_max_segs is written under RTNL protection, or when the device is not yet visible, but is read locklessly. Add netif_set_gso_max_segs() helper. Add the READ_ONCE()/WRITE_ONCE() pairs, and use netif_set_gso_max_segs() where we can to better document what is going on. Signed-off-by:

Guangbin Huang says: ==================== ethtool: add support to set/get tx copybreak buf size and rx buf len This series add support to set/get tx copybreak buf size and rx buf len via ethtool and hns3 driver implements them. Tx copybreak buf size is used for tx copybreak feature which for small size packet or frag. Use ethtool --get-tunable command to get it, and ethtool --set-tunable command to set it, examples are as follow: 1. set tx spare buf size to 102400: $ ethtool --set-tunable eth1 tx-buf-size 102400 2. get tx spare buf size: $ ethtool --get-tunable eth1 tx-buf-size tx-buf-size: 102400 Rx buf len is buffer length of each rx BD. Use ethtool -g command to get it, and ethtool -G command to set it, examples are as follow: 1. set rx buf len to 4096 $ ethtool -G eth1 rx-buf-len 4096 2. get rx buf len $ ethtool -g eth1 ... RX Buf Len: 4096 Change log: V5 -> V6 1.Fix compile error for divers/s390. V4 -> V5 1.Change struct ethtool_ringparam_ext to kernel_ethtool_ringparam. 2.change "__u32 rx_buf_len" to "u32 rx_buf_len". V3 -> V4 1.Fix a few allmodconfig compile warning. 2.Add more '=' synbol to ethtool-netlink.rst to refine format. 3.Move definement of struct ethtool_ringparam_ext to include/linux/ethtool.h. 4.Move related modify of rings_fill_reply() from patch 4/6 to patch 3/6. V2 -> V3 1.Remove documentation for tx copybreak buf size, there is description for it in userspace ethtool. 2.Move extending parameters for get/set_ringparam function from patch3/6 to patch 4/6. V1 -> V2 1.Add documentation for rx buf len and tx copybreak buf size. 2.Extend structure ringparam_ext for extenal ring params. 3.Change type of ETHTOOL_A_RINGS_RX_BUF_LEN from NLA_U32 to NLA_POLICY_MIN(NLA_U32, 1). 4.Add supported_ring_params in ethtool_ops to indicate if support external params. ==================== Signed-off-by: -

Tx copybreak buf size is used for tx copybreak feature, the feature is used for small size packet or frag. 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. Signed-off-by:

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: -

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:

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/220Signed-off-by:

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. Signed-off-by:

Add support for the TI DP83561-SP Gigabit ethernet phy device. The dp83561-sp is a radiation hardened space grade gigabit ethernet PHY. It has been tested for single event latch upto 121 MeV, the critical reliability parameter for space designs. It interfaces directly to twisted pair media through an external transformer. And the device also interfaces directly to the MAC layer through Reduced GMII (RGMII) and MII. DP83867, DP83869 and DP83561-SP, all these parts support 1000Base-T/ 100Base-TX/ and 10Base-Te standards and have similar register map for the core functionality.
