Call phy_disable_interrupts() in phy_init_hw() to "have a defined init state as we don't know in which state the PHY is if the PHY driver is loaded. We shouldn't assume that it's the chip power-on defaults, BIOS or boot loader could have changed this. Or in case of dual-boot systems the other OS could leave the PHY in whatever state." as pointed out by Heiner. Suggested-by:

We face an issue with rtl8211f, a pin is shared between INTB and PMEB, and the PHY Register Accessible Interrupt is enabled by default, so the INTB/PMEB pin is always active in polling mode case. As Heiner pointed out "I was thinking about calling phy_disable_interrupts() in phy_init_hw(), to have a defined init state as we don't know in which state the PHY is if the PHY driver is loaded. We shouldn't assume that it's the chip power-on defaults, BIOS or boot loader could have changed this. Or in case of dual-boot systems the other OS could leave the PHY in whatever state." Make phy_disable_interrupts() non-static so that it could be used in phy_init_hw() to have a defined init state. Suggested-by:

When writing the serdes configuration register was moved to mvneta_config_interface() the whole code block was removed from mvneta_port_power_up() in the assumption that its only purpose was to write the serdes configuration register. As mentioned by Russell King its purpose was also to check for valid interface modes early so that later in the driver we do not have to care for unexpected interface modes. Add back the test to let the driver bail out early on unhandled interface modes. Fixes: b4748553 ("net: ethernet: mvneta: Fix Serdes configuration for SoCs without comphy") Signed-off-by:

In mvneta_config_interface() the RGMII modes are catched by the default case which is an error return. The RGMII modes are valid modes for the driver, so instead of returning an error add a break statement to return successfully. This avoids this warning for non comphy SoCs which use RGMII, like SolidRun Clearfog: WARNING: CPU: 0 PID: 268 at drivers/net/ethernet/marvell/mvneta.c:3512 mvneta_start_dev+0x220/0x23c Fixes: b4748553 ("net: ethernet: mvneta: Fix Serdes configuration for SoCs without comphy") Signed-off-by:

The driver for Marvell switches puts all ports in IGMP snooping mode which results in all IGMP/MLD frames that ingress on the ports to be forwarded to the CPU only. The bridge code in the kernel can then interpret these frames and act upon them, for instance by updating the mdb in the switch to reflect multicast memberships of stations connected to the ports. However, the IGMP/MLD frames must then also be forwarded to other ports of the bridge so external IGMP queriers can track membership reports, and external multicast clients can receive query reports from foreign IGMP queriers. Currently, this is impossible as the EDSA tagger sets offload_fwd_mark on the skb when it unwraps the tagged frames, and that will make the switchdev layer prevent the skb from egressing on any other port of the same switch. To fix that, look at the To_CPU code in the DSA header and make forwarding of the frame possible for trapped IGMP packets. Introduce some #defines for the frame types to make the code a bit more comprehensive. This was tested on a Marvell 88E6352 variant. Signed-off-by:

ovs connection tracking module performs de-fragmentation on incoming fragmented traffic. Take info account if traffic has been de-fragmented in execute_check_pkt_len action otherwise we will perform the wrong nested action considering the original packet size. This issue typically occurs if ovs-vswitchd adds a rule in the pipeline that requires connection tracking (e.g. OVN stateful ACLs) before execute_check_pkt_len action. Moreover take into account GSO fragment size for GSO packet in execute_check_pkt_len routine Fixes: 4d5ec89f ("net: openvswitch: Add a new action check_pkt_len") Signed-off-by:

Russell King says: ==================== Two phylink pause fixes While testing, I discovered two issues with ethtool -A with phylink. First, if there is a PHY bound to the network device, we hit a deadlock when phylib tries to notify us of the link changing as a result of triggering a renegotiation. Second, when we are manually forcing the pause settings, and there is no renegotiation triggered, we do not update the MAC via the new mac_link_up approach. These two patches solve both problems, and will need to be backported to v5.7; they do not apply cleanly there due to the introduction of PCS in the v5.8 merge window. ==================== Signed-off-by: -
Russell King authored
We have been relying on link events and mac_config() when the manual pause modes are changed. With recent developments, such as moving the programming of link state to mac_link_up(), this no longer works. To ensure that we update the MAC, we must generate a link-down followed by a link-up event; we can do that by setting mac_link_dropped and triggering a resolve.

Clearing the sock TX queue in sk_set_socket() might cause unexpected out-of-order transmit when called from sock_orphan(), as outstanding packets can pick a different TX queue and bypass the ones already queued. This is undesired in general. More specifically, it breaks the in-order scheduling property guarantee for device-offloaded TLS sockets. Remove the call to sk_tx_queue_clear() in sk_set_socket(), and add it explicitly only where needed. Fixes: e022f0b4 ("net: Introduce sk_tx_queue_mapping") Signed-off-by:

The first patch stores the firmware version code which is needed by the next 2 patches to determine some worarounds based on the firmware version. The workarounds are to disable legacy TX push mode and to clear the hardware statistics during ifdown. The last patch checks that it is a PF before reading the VPD.

On older firmware, the hardware statistics are not cleared when the driver frees the hardware stats contexts during ifdown. The driver expects these stats to be cleared and saves a copy before freeing the stats contexts. During the next ifup, the driver will likely allocate the same hardware stats contexts and this will cause a big increase in the counters as the old counters are added back to the saved counters. We fix it by making an additional firmware call to clear the counters before freeing the hw stats contexts when the firmware is the older 20.x firmware.
