Subject: [net-next v2 00/11][pull request] Intel Wired LAN Driver Updates 2014-11-18

This series contains updates to i40e only.

Shannon provides a patch to clean up the driver to only warn once that
PTP is not supported when linked at 100Mbps.

Mitch provides a fix for i40e where the VF interrupt processing takes
a long time and it is possible that we could lose a VFLR event if it
happens while processing a VFLR on another VF.  To correct this situation,
we enable the VFLR interrupt cause before we begin processing any pending
resets.

Neerav provides several patches to update DCB support in i40e.  When
there are DCB configuration changes based on DCBx, the firmware suspends
the port's Tx and generates an event to the PF.  The PF is then
responsible to reconfigure the PF VSIs and switching topology as per the
updated DCB configuration and then resume the port's Tx by calling the
"Resume Port Tx" AQ command, so add this call to the flow that handles
DCB re-configuration in the PF.  Allow the driver to query and use DCB
configuration from firmware when firmware DCBx agent is in CEE mode.
Add a check whether LLDP Agent's default AdminStatus is enabled or
disabled on a given port, and sets DCBx status to disabled if the
status is disabled.  Fix an issue when the port TC configuration
changes as a result of DCBx and the driver modifies the enabled TCs for
the VEBs it manages but does not update the enabled_tc value that 
was cached on a per VEB basis.  Add a new PF state so that if a port's
Tx is in suspended state the Tx queue disable flow would just put the
request for the queue to be disabled and return without waiting for the
queue to be actually disabled.  Allows the driver to enable/disable
the XPS based on the number of TCs being enabled for the given VSI.

v2: Dropped patch "i40e: Handle a single mss packet with more than 8 frags"
    while we rework the patch after we test a bit more based on feedback from 
    Eric Dumazet.
