      mt76: mt7615: reduce maximum VHT MPDU length to 7991 · efb16763
      Felix Fietkau authored
      After fixing mac80211 to allow larger A-MSDUs in some cases, there have been
      reports of performance regressions and packet loss with some clients.
      It appears that the issue occurs when the hardware is transmitting A-MSDUs
      bigger than 8k. Limit the local VHT MPDU size capability to 7991, matching
      the value used for MT7915 as well.

      net: stmmac: removed enabling eee in EEE set callback · 7241c5a6
      Voon Weifeng authored
      EEE should be only be enabled during stmmac_mac_link_up() when the
      link are up and being set up properly. set_eee should only do settings
      configuration and disabling the eee.
      
      Without this fix, turning on EEE using ethtool will return
      "Operation not supported". This is due to the driver is in a dead loop
      waiting for eee to be advertised in the for eee to be activated but the
      driver will only configure the EEE advertisement after the eee is
      activated.
      
      Ethtool should only return "Operation not supported" if there is no EEE
      capbility in the MAC controller.

      net: lantiq: Add locking for TX DMA channel · f9317ae5
      Hauke Mehrtens authored
      The TX DMA channel data is accessed by the xrx200_start_xmit() and the
      xrx200_tx_housekeeping() function from different threads. Make sure the
      accesses are synchronized by acquiring the netif_tx_lock() in the
      xrx200_tx_housekeeping() function too. This lock is acquired by the
      kernel before calling xrx200_start_xmit().

      Revert "ravb: Fixed to be able to unload modules" · 77972b55
      Geert Uytterhoeven authored
      This reverts commit 1838d6c6.
      
      This commit moved the ravb_mdio_init() call (and thus the
      of_mdiobus_register() call) from the ravb_probe() to the ravb_open()
      call.  This causes a regression during system resume (s2idle/s2ram), as
      new PHY devices cannot be bound while suspended.
      
      During boot, the Micrel PHY is detected like this:
      
          Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00: attached PHY driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=e6800000.ethernet-ffffffff:00, irq=228)
          ravb e6800000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off
      
      During system suspend, (A) defer_all_probes is set to true, and (B)
      usermodehelper_disabled is set to UMH_DISABLED, to avoid drivers being
      probed while suspended.
      
        A. If CONFIG_MODULES=n, phy_device_register() calling device_add()
           merely adds the device, but does not probe it yet, as
           really_probe() returns early due to defer_all_probes being set:
      
             dpm_resume+0x128/0x4f8
      	 device_resume+0xcc/0x1b0
      	   dpm_run_callback+0x74/0x340
      	     ravb_resume+0x190/0x1b8
      	       ravb_open+0x84/0x770
      		 of_mdiobus_register+0x1e0/0x468
      		   of_mdiobus_register_phy+0x1b8/0x250
      		     of_mdiobus_phy_device_register+0x178/0x1e8
      		       phy_device_register+0x114/0x1b8
      			 device_add+0x3d4/0x798
      			   bus_probe_device+0x98/0xa0
      			     device_initial_probe+0x10/0x18
      			       __device_attach+0xe4/0x140
      				 bus_for_each_drv+0x64/0xc8
      				   __device_attach_driver+0xb8/0xe0
      				     driver_probe_device.part.11+0xc4/0xd8
      				       really_probe+0x32c/0x3b8
      
           Later, phy_attach_direct() notices no PHY driver has been bound,
           and falls back to the Generic PHY, leading to degraded operation:
      
             Generic PHY e6800000.ethernet-ffffffff:00: attached PHY driver [Generic PHY] (mii_bus:phy_addr=e6800000.ethernet-ffffffff:00, irq=POLL)
             ravb e6800000.ethernet eth0: Link is Up - 1Gbps/Full - flow control off
      
        B. If CONFIG_MODULES=y, request_module() returns early with -EBUSY due
           to UMH_DISABLED, and MDIO initialization fails completely:
      
             mdio_bus e6800000.ethernet-ffffffff:00: error -16 loading PHY driver module for ID 0x00221622
             ravb e6800000.ethernet eth0: failed to initialize MDIO
             PM: dpm_run_callback(): ravb_resume+0x0/0x1b8 returns -16
             PM: Device e6800000.ethernet failed to resume: error -16
      
           Ignoring -EBUSY in phy_request_driver_module(), like was done for
           -ENOENT in commit 21e19442 ("net: phy: fix issue with loading
           PHY driver w/o initramfs"), would makes it fall back to the Generic
           PHY, like in the CONFIG_MODULES=n case.

      mptcp: Wake up MPTCP worker when DATA_FIN found on a TCP FIN packet · ef59b195
      Mat Martineau authored
      When receiving a DATA_FIN MPTCP option on a TCP FIN packet, the DATA_FIN
      information would be stored but the MPTCP worker did not get
      scheduled. In turn, the MPTCP socket state would remain in
      TCP_ESTABLISHED and no blocked operations would be awakened.
      
      TCP FIN packets are seen by the MPTCP socket when moving skbs out of the
      subflow receive queues, so schedule the MPTCP worker when a skb with
      DATA_FIN but no data payload is moved from a subflow queue. Other cases
      (DATA_FIN on a bare TCP ACK or on a packet with data payload) are
      already handled.
      
      Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/84
      Fixes: 43b54c6e ("mptcp: Use full MPTCP-level disconnect state machine")
