      net: hns3: VF not request link status when PF support push link status feature · 01305e16
      由 Guangbin Huang 提交于 
      To reduce the processing of unnecessary mailbox command when PF supports
actively push its link status to VFs, VFs stop sending request link
status command in periodic service task in this case.

      net: hns3: PF add support for pushing link status to VFs · 18b6e31f
      由 Guangbin Huang 提交于 
      Previously, VF updates its link status every second by send query command
to PF in periodic service task. If link stats of PF is changed, VF may
need at most one second to update its link status.

To reduce delay of link status between PF and VFs, PF actively push its
link status to VFs when its link status is updated. And to let VF know
PF supports this new feature, the link status changed mailbox command
adds one bit to indicate it.

      net: phy: at803x: select correct page on config init · c329e5af
      由 David Bauer 提交于 
      The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber
as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit
in the chip configure register.

The driver assumes the copper side is selected on probe, but this might
not be the case depending which page was last selected by the
bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior.

Select the copper page when probing to circumvent this.

====================
100GbE Intel Wired LAN Driver Updates 2021-04-14

This series contains updates to ice driver only.

Bruce changes and removes open coded values to instead use existing
kernel defines and suppresses false cppcheck issues.

Ani adds new VSI states to track netdev allocation and registration. He
also removes leading underscores in the ice_pf_state enum.

Jesse refactors ITR by introducing helpers to reduce duplicated code and
structures to simplify checking of ITR mode. He also triggers a software
interrupt when exiting napi poll or busy-poll to ensure all work is
processed. Modifies /proc/iomem to display driver name instead of PCI
address. He also changes the checks of vsi->type to use a local variable
in ice_vsi_rebuild() and removes an unneeded struct member.

Jake replaces the driver's adaptive interrupt moderation algorithm to
use the kernel's DIM library implementation.

Scott reworks module reads to reduce the number of reads needed and
remove excessive increment of QSFP page.

Brett sets the vsi->vf_id to invalid for non-VF VSIs.

Paul removes the return value from ice_vsi_manage_rss_lut() as it's not
communicating anything critical. He also reduces the scope of a
variable.
