2013-07-28e1000e: fix I217/I218 PHY initialization flowBruce Allan
The initialization of the PHY on I217/I218, while similar to 82579, must also check to see if the MAC and PHY are in the same mode (PCIe vs. SMBus) otherwise the PHY will be inaccessible by the MAC.

2013-07-28e1000e: do not resume device from RPM suspend to read PHY status registersBruce Allan
When the device is runtime suspended (e.g. when there is no link), do not wake it from D3 to read the PHY status; just set the values to typical power-on defaults as is done when runtime PM is not enabled and there is no link.

The device IDs 0x15a0 and 0x15a1 are new SKUs that contain the same MAC as I217 and same PHY as I218. The device IDs 0x15a2 and 0x15a3 are the same as existing I218 SKUs.

2013-07-28e1000e: ethtool unnecessarily takes device out of RPM suspendBruce Allan
A previous patch (commit e60b22c5b7 e1000e: fix accessing to suspended device) added .begin and .complete ethtool driver callbacks so that the device was resumed from Runtime Power Management (RPM) suspend state for all ethtool operations. This is overkill for operations which do not need to access any registers in the device. This patch makes it so that the device is taken out of RPM suspend only for those ethtool operations that must access device registers.

2013-07-28e1000e: Tx hang on I218 when linked at 100Half and slow response at 10MbpsBruce Allan
Tx hang is an unintended consequence of another workaround that is in the EEPROM for an issue with the firmware at 10Mbps when K1 (a power mode of the MAC-PHY interconnect) is enabled. The issue is resolved by setting appropriate Tx re-transmission timeouts in the PHY and associated K1 entry times in the MAC to allow enough transmissions to occur without triggering a Tx hang. A similar change is needed when linked at 10Mbps to improve latency.

2013-07-28e1000e: iAMT connections drop on driver unload when jumbo frames enabledBruce Allan
The jumbo frame configuration in the MAC/PHY should be reverted on 82579 and newer parts when the interface is brought down (not just when the MTU is changed back to standard frame size) otherwise iAMT connections (e.g. SoL, IDE-R) will be dropped and cannot be re-acquired until the MTU is changed again.

2013-07-28e1000e: restore call to pci_clear_master()Dean Nelson
In attempting to resolve a minor merge conflict, commit e5f2ef7ab4690d2e8faa (Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net) accidentally dropped a call to pci_clear_master() that was intended to remain in place. Commit 4e0855dff094b0d56d6b (e1000e: fix pci-device enable-counter balance) replaced a call to pci_disable_device() by one to pci_clear_master(). And then commit 66148babe728f3e00e13 (e1000e: fix runtime power management transitions) deleted a number of lines starting two lines following that call.

2013-07-27USBNET: centralize computing of max rx/tx qlenMing Lei
This patch centralizes computing of max rx/tx qlen, because: - RX_QLEN()/TX_QLEN() is called in hot path - computing depends on device's usb speed, now we have ls/fs, hs, ss, so more checks need to be involved - in fact, max rx/tx qlen should not only depend on device USB speed, but also depend on ethernet link speed, so we need to consider that in future. - if SG support is done, max tx qlen may need change too Generally, hard_mtu and rx_urb_size are changed in bind(), reset() and link_reset() callback, and change mtu network operation, this patches introduces the API of usbnet_update_max_qlen(), and calls it in above path.

2013-07-27tuntap: hardware vlan tx supportJason Wang
Inspired by commit f09e2249c4f5c7c13261ec73f5a7807076af0c8e (macvtap: restore vlan header on user read). This patch adds hardware vlan tx support for tuntap. This is done by copying vlan header directly into userspace in tun_put_user() instead of doing it through __vlan_put_tag() in dev_hard_start_xmit(). This eliminates one unnecessary memmove() in vlan_insert_tag() for 802.1ad and 802.1q traffic. pktgen test shows about 20% improvement for 802.1q traffic: Before: 662149pps 317Mb/sec (317831520bps) errors: 0 After: 801033pps 384Mb/sec (384495840bps) errors: 0 Cc: Basil Gor <basil.gor@gmail.com> Cc: Michael S.

2013-07-25pch_gbe: Add MinnowBoard supportDarren Hart
The MinnowBoard uses an AR803x PHY with the PCH GBE which requires special handling. Use the MinnowBoard PCI Subsystem ID to detect this and add a pci_device_id.driver_data structure and functions to handle platform setup. The AR803x does not implement the RGMII 2ns TX clock delay in the trace routing nor via strapping. Add a detection method for the board and the PHY and enable the TX clock delay via the registers. This PHY will hibernate without link for 10 seconds. Ensure the PHY is awake for probe and then disable hibernation. A future improvement would be to convert pch_gbe to using PHYLIB and making sure we can wake the PHY at the necessary times rather than permanently disabling it.
