      e1000e: Fix TSO with non-accelerated vlans · 47ccd1ed
      Vlad Yasevich authored
      
      
      This device claims  TSO support for vlans.  It also allows a
      user to control vlan acceleration offloading.  As such, it is
      possible to turn off vlan acceleration and configure a vlan
      which will continue to support TSO.
      
      In such situation the packet passed down the the device will contain
      a vlan header and skb->protocol will be set to ETH_P_8021Q.
      The device assumes that skb->protocol contains network protocol
      value and uses that value to set up TSO information.  This results
      in corrupted frames sent on the wire.  Corruptions include
      incorrect IP total length and invalid IP checksum.
      
      This patch extract the protocol value correctly and corrects TSO
      for non-accelerated traffic.

      e1000e: Fix no connectivity when driver loaded with cable out · b20a7744
      David Ertman authored
      In commit da1e2046
      
      , the flow for enabling/disabling an Si errata
      workaround (e1000_lv_jumbo_workaround_ich8lan) was changed to fix a problem
      with iAMT connections dropping on interface down with jumbo frames set.
      Part of this change was to move the function call disabling the workaround
      to e1000e_down() from the e1000_setup_rctl() function.  The mechanic for
      disabling of this workaround involves writing several MAC and PHY registers
      back to hardware defaults.
      
      After this commit, when the driver is loaded with the cable out, the PHY
      registers are not programmed with the correct default values.  This causes
      the device to be capable of transmitting packets, but is unable to recieve
      them until this workaround is called.
      
      The flow of e1000e's open code relies upon calling the above workaround to
      expicitly program these registers either with jumbo frame appropriate settings
      or h/w defaults on 82579 and newer hardware.
      
      Fix this issue by adding logic to e1000_setup_rctl() that not only calls
      e1000_lv_jumbo_workaround_ich8lan() when jumbo frames are set, to enable the
      workaround, but also calls this function to explicitly disable the workaround
      in the case that jumbo frames are not set.
