This hack (affecting the non-PCIe models only) was introduced in 2004 to deal with link negotiation failures in 1GBit mode. Based on a comment in the r8169 vendor driver I assume the issue affects RTL8169sb in combination with particular 1GBit switch models. Resetting the PHY every 10s and hoping that one fine day we will make it to establish the link seems to be very hacky to me. I'd say: If 1GBit doesn't work reliably in a users environment then the user should remove 1GBit from the advertised modes, e.g. by using ethtool -s <if> advertise <10/100 modes> If the issue affects one chip version only and that with most link partners, then we could also think of removing 1GBit from the advertised modes for this chip version in the driver.

After we change the ipvlan mode from l3 to l2, or vice versa, we only reset IFF_NOARP flag, but don't flush the ARP table cache, which will cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2(). Then the message will not come out of host. Here is the reproducer on local host: ip link set eth1 up ip addr add 192.168.1.1/24 dev eth1 ip link add link eth1 ipvlan1 type ipvlan mode l3 ip netns add net1 ip link set ipvlan1 netns net1 ip netns exec net1 ip link set ipvlan1 up ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1 ip route add 192.168.2.0/24 via 192.168.1.2 ping 192.168.2.2 -c 2 ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2 ping 192.168.2.2 -c 2 Add the same configuration on remote host. After we set the mode to l2, we could find that the src/dst MAC addresses are the same on eth1: 21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64 Fix this by calling dev_change_flags(), which will call netdevice notifier with flag change info. v2: a) As pointed out by Wang Cong, check return value for dev_change_flags() when change dev flags. b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops.

Since the addition of GRO for ESP, gro_receive can consume the skb and return -EINPROGRESS. In that case, the lower layer GRO handler cannot touch the skb anymore. Commit 5f114163 ("net: Add a skb_gro_flush_final helper.") converted some of the gro_receive handlers that can lead to ESP's gro_receive so that they wouldn't access the skb when -EINPROGRESS is returned, but missed other spots, mainly in tunneling protocols. This patch finishes the conversion to using skb_gro_flush_final(), and adds a new helper, skb_gro_flush_final_remcsum(), used in VXLAN and GUE.

Amritha Nambiar says: ==================== Symmetric queue selection using XPS for Rx queues This patch series implements support for Tx queue selection based on Rx queue(s) map. This is done by configuring Rx queue(s) map per Tx-queue using sysfs attribute. If the user configuration for Rx queues does not apply, then the Tx queue selection falls back to XPS using CPUs and finally to hashing. XPS is refactored to support Tx queue selection based on either the CPUs map or the Rx-queues map. The config option CONFIG_XPS needs to be enabled. By default no receive queues are configured for the Tx queue. - /sys/class/net/<dev>/queues/tx-*/xps_rxqs A set of receive queues can be mapped to a set of transmit queues (many:many), although the common use case is a 1:1 mapping. This will enable sending packets on the same Tx-Rx queue association as this is useful for busy polling multi-threaded workloads where it is not possible to pin the threads to a CPU.
