====================
Intel Wired LAN Driver Updates 2014-06-11
This series contains updates to igb, i40e and i40evf.
Todd makes a change to igb to un-hide invariant returns by getting rid of
the E1000_SUCCESS define and converting those returns to return 0.
Jacob separates the hardware logic from the set function, so that we can
re-use it during a ptp_reset in igb. This enables the reset to return
functionality to the last know timestamp mode, rather than resetting the
value.
Ashish implements context flags for headwb and headwb_addr so that we
do not have to keep them always enabled.
Shannon updates the admin queue API for the new firmware, which adds
set_pf_content, nvm_config_read/write, replaces set_phy_reset with
set_phy_debug and removes nvm_read/write_reg_se. Cleans up the driver
to use the stored base_queue value since there is no need to read the
PCI register for the PF's base queue on every single transmit queue
enable and disable as we already have the value stored from reading
the capability features at startup.
Anjali changes the notion of source and destination for FD_SB in ethtool
to align i40e with other drivers. Adds flow director statistics to
the PF stats. Fixes a bug in ethtool for flow director drop packet
filter where the drop action comes down as a ring_cookie value, so allow
it as a special value that can be used to configure destination control.
Mitch fixes the i40evf to keep the driver from going down when it is
already in a down state. This prevents a CPU soft lock in napi_disable().
Also change the i40evf to check the admin queue error bits since the
firmware can indicate any admin queue error states to the driver via
some bits in the length registers.
Neerav separates out the DCB capability and enabled flags because currently
if the firmware reports DCB capability the driver enables
I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver inserts
a tag when transmitting a packet from the port even if there are no DCB
traffic classes configured at the port. So by adding the additional flag,
I40E_FLAG_DCB_CAPABLE, that will be set when the DCB capability is present
and the existing enabled flag will only be set if there are more than one
traffic classes configured at the port.
Greg fixes the i40e driver to not automatically accept tagged packets by
default so that the system must request a VLAN tag packet filter to get
packets with that tag. Greg also converts i40e to use the in-kernel
ether_addr_copy() instead of mempcy().
Jesse removes the FTYPE field from the receive descriptor to match the
hardware implementation.
