Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (84 commits) wimax: fix kernel-doc for debufs_dentry member of struct wimax_dev net: convert pegasus driver to net_device_ops bnx2x: Prevent eeprom set when driver is down net: switch kaweth driver to netdevops pcnet32: round off carrier watch timer i2400m/usb: wrap USB power saving in #ifdef CONFIG_PM wimax: testing for rfkill support should also test for CONFIG_RFKILL_MODULE wimax: fix kconfig interactions with rfkill and input layers wimax: fix '#ifndef CONFIG_BUG' layout to avoid warning r6040: bump release number to 0.20 r6040: warn about MAC address being unset r6040: check PHY status when bringing interface up r6040: make printks consistent with DRV_NAME gianfar: Fixup use of BUS_ID_SIZE mlx4_en: Returning real Max in get_ringparam mlx4_en: Consider inline packets on completion netdev: bfin_mac: enable bfin_mac net dev driver for BF51x qeth: convert to net_device_ops vlan: add neigh_setup dm9601: warn on invalid mac address ...
