      tg3: missing break statement in tg3_get_5720_nvram_info() · 17e1a42f
      由 Dan Carpenter 提交于 
      There is a missing break statement so FLASH_5762_EEPROM_HD gets treated
like FLASH_5762_EEPROM_LD.

      net: Add support for XPS without sysfs being defined · 024e9679
      由 Alexander Duyck 提交于 
      This patch makes it so that we can support transmit packet steering without
sysfs needing to be enabled.  The reason for making this change is to make
it so that a driver can make use of the XPS even while the sysfs portion of
the interface is not present.

      net: Rewrite netif_set_xps_queues to address several issues · 01c5f864
      由 Alexander Duyck 提交于 
      This change is meant to address several issues I found within the
netif_set_xps_queues function.

If the allocation of one of the maps to be assigned to new_dev_maps failed
we could end up with the device map in an inconsistent state since we had
already worked through a number of CPUs and removed or added the queue.  To
address that I split the process into several steps.  The first of which is
just the allocation of updated maps for CPUs that will need larger maps to
store the queue.  By doing this we can fail gracefully without actually
altering the contents of the current device map.

The second issue I found was the fact that we were always allocating a new
device map even if we were not adding any queues.  I have updated the code
so that we only allocate a new device map if we are adding queues,
otherwise if we are not adding any queues to CPUs we just skip to the
removal process.

The last change I made was to reuse the code from remove_xps_queue to remove
the queue from the CPU.  By making this change we can be consistent in how
we go about adding and removing the queues from the CPUs.

      net: Rewrite netif_reset_xps_queue to allow for better code reuse · 10cdc3f3
      由 Alexander Duyck 提交于 
      This patch does a minor refactor on netif_reset_xps_queue to address a few
items I noticed.

First is the fact that we are doing removal of queues in both
netif_reset_xps_queue and netif_set_xps_queue.  Since there is no need to
have the code in two places I am pushing it out into a separate function
and will come back in another patch and reuse the code in
netif_set_xps_queue.

The second item this change addresses is the fact that the Tx queues were
not getting their numa_node value cleared as a part of the XPS queue reset.
This patch resolves that by resetting the numa_node value if the dev_maps
value is set.
