* 'upstream-linus' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/netdev-2.6:
  Revert "drivers/net/pcmcia/3c589_cs: fix port configuration switcheroo"
  sky2: be more selective about FIFO watchdog
  sky2: FE+ Phy initialization
  r8169: workaround against ignored TxPoll writes (8168)
  r8169: correct phy parameters for the 8110SC
parents bbbd2bf0 402c79fb
