Jeff Kirsher says:

====================
This series contains updates to ixgbe.

Jacob provides a fix for 82599 devices where it can potentially keep link
lights up when the adapter has gone down.

Mark provides a fix to resolve the possible use of uninitialized memory
by checking the return value on EEPROM reads.

Don provides 2 patches, one to fix a issue where we were traversing the
Tx ring with the value of IXGBE_NUM_RX_QUEUES which currently happens
to have the correct value but this is misleading.  A change later, could
easily make this no longer correct so when traversing the Tx ring, use
netdev->num_tx_queues.  His second patch does some minor clean ups of log
messages.

Emil provides the remaining ixgbe patches.  First he fixes the link test
where forcing the laser before the link check can lead to inconsistent
results because it does not guarantee that the link will be negotiated
correctly.  Then he initializes the message buffer array to 0 in order
to avoid using random numbers from the memory as a MAC address for the
VF.  Emil also fixes the read loop for the I2C data to account for the
offset for SFP+ modules.  Lastly, Emil provides several patches to add
support for QSFP modules where 1Gbps support is added as well as support
for older QSFP active direct attach cables which pre-date SFF-8436 v3.6.

v2: Fixed patch 4 description and added blank line based on feedback from
    Sergei Shtylyov
