      de2104x: support for systems lacking cache coherence · b77e5228
      Risto Suominen authored
      Add a configurable Descriptor Skip Length for systems that lack cache
      coherence.
      
      (akpm: I think this should be done as a module parameter, not a
      compile-tinme option)

      drivers/net/macvlan.c: fix cloning of tagged VLAN interfaces · ef5c8996
      sg.tweak@gmail.com authored
      Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13348
      
      akpm: the reporter disappeared, so I typed it in again.
      
      It is not possible to make clone of tagged VLAN interface to be used as
      mac-based vlan interfave.
      
      How reproducible:
      Use any 802.1q tagged vlan interface, e.g. eth2.700 and clone it:
      
        ip link add link eth2.700 address 00:04:75:cb:38:09 macvlan0 type macvlan
        ip link set dev macvlan0 up
        ip addr add 10.195.1.1/24 dev macvlan0
      
      So far, so good. Now try to ping anything via macvlan0:
      
        ping 10.195.1.2
      
      Actual results:
      For every attempted packet tx kernel writes to console:

      Macvlan driver always uses standard ethernet header length for all types
      of interface to which it is linked.  This patch fixes this problem.

      e100: add non-MII PHY support · 72001762
      Andreas Mohr authored
      Restore support for cards with MII-lacking PHYs as compared to removed
      pre-2.6.29 eepro100 driver: use full low-level MII I/O access abstraction
      by providing clean PHY-specific mdio_ctrl() functions for either standard
      MII-compliant cards, slightly special ones or non-MII PHY ones.
      
      We now have another netdev_priv member for mdio_ctrl(), thus we have some
      array indirection, but we save some additional opcodes for specific
      phy_82552_v handling in the common case.
