      ixgbe: Remove MAC X550EM_X 1Gbase-t led_[on|off] support · 5e999fb4
      Paul Greenwalt authored
      Since FW configures the PHY and MAC X550EM_X has no
      PHY access, led_[on|off] is not supported with the 1Gbase-t design.
      
      Removed MAC X550EM_X 1Gbase-t led_[on|off] support by setting
      function pointers to NULL and added NULL pointer checks. Also set
      init_led_link_act to NULL and added NULL pointer check.

      This CallTrace occurred on 32-bit kernel with CONFIG_PROVE_LOCKING
      enabled.
      
      This happens at ixgbe driver probe hardware stage, when comes to
      ixgbe_get_stats64, the seqcount/seqlock still not initialize, although
      this was initialize in TX/RX resources setup routin, but it was too late,
      then lockdep give this Warning.
      
      To fix this, move the u64_stats_init function to driver probe stage,
      which before we get the status of seqcount and after the RX/TX ring
      was finished init.

      ixgbe/ixgbevf: Enables TSO for MPLS encapsulated packets · 2a20525b
      Scott Peterson authored
      This patch advertises TSO & GSO features in netdev->mpls_features.
      In ixgbe(vf)_tso() where we set up segmentation offload, the IP
      header will be the inner network header when eth_p_mpls() indicates
      the Ethernet protocol is MPLS (UC or MC).

      bnxt_en: Fix xmit_more with BQL. · ffe40645
      Michael Chan authored
      We need to write the doorbell if BQL has stopped the queue and
      skb->xmit_more is set.  Otherwise it is possible for the tx queue to
      rot and cause tx timeout.
      
      Fixes: 4d172f21 ("bnxt_en: Implement xmit_more.")
