Pull networking fixes from David Miller:
 "Just a pile of random fixes, including:

   1) Do not apply TSO limits to non-TSO packets, fix from Herbert Xu.

   2) MDI{,X} eeprom check in e100 driver is reversed, from John W.
      Linville.

   3) Missing error return assignments in several ethernet drivers, from
      Julia Lawall.

   4) Altera TSE device doesn't come back up after ifconfig down/up
      sequence, fix from Kostya Belezko.

   5) Add more cases to the check for whether the qmi_wwan device has a
      bogus MAC address and needs to be assigned a random one.  From
      Kristian Evensen.

   6) Fix interrupt hangs in CPSW, from Felipe Balbi.

   7) Implement ndo_features_check in r8152 so that the stack doesn't
      feed GSO packets which are outside of the chip's capabilities.
      From Hayes Wang"
