      net: xilinx: constify net_device_ops structure · 10eeb5e6
      由 Bhumika Goyal 提交于 
      Declare net_device_ops structure as const as it is only stored in
the netdev_ops field of a net_device structure. This field is of type
const, so net_device_ops structures having same properties can be made
const too.

      net: qcom/emac: claim the irq only when the device is opened · 4404323c
      由 Timur Tabi 提交于 
      During reset, functions emac_mac_down() and emac_mac_up() are called,
so we don't want to free and claim the IRQ unnecessarily.  Move those
operations to open/close.

      net: qcom/emac: rename emac_phy to emac_sgmii and move it · 41c1093f
      由 Timur Tabi 提交于 
      The EMAC has an internal PHY that is often called the "SGMII".  This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion.  In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.

Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only.  It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).

To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

      bnx2x: avoid two atomic ops per page on x86 · b9032741
      由 Eric Dumazet 提交于 
      Commit 4cace675 ("bnx2x: Alloc 4k fragment for each rx ring buffer
element") added extra put_page() and get_page() calls on arches where
PAGE_SIZE=4K like x86

Reorder things to avoid this overhead.
