Add XDP support to the IGB driver.
The implementation follows the IXGBE XDP implementation
closely and I used the following patches as basis:
1. commit 924708081629 ("ixgbe: add XDP support for pass and drop actions")
2. commit 33fdc82f0883 ("ixgbe: add support for XDP_TX action")
3. commit ed93a3

Insert the full 16 bit VIF ID into ipmr Netlink cache reports.
If using more than 255 multicast interfaces it is necessary to have
access to a VIF ID for cache reports that is wider than 8 bits, the
VIF ID present in the igmpmsg reports sent to mroute_sk are only 8
bits wide in the igmpmsg header.
Insert the multicast route table ID as a Netlink attribute to Netlink
cache report notifications.
When multiple route tables are in use it is necessary to have a way to
determine which route table a given cache report belongs to when
receiving the cache report.

Currently it is not possible to use more than 255 multicast interfaces
for IPv4 due to the format of the igmpmsg header which only has 8 bits
available for the VIF ID. There is enough space for the full VIF ID in
the Netlink cache notifications, however the value is currently taken
directly from t

must be called first, followed by rtl8366_set_vlan(),

Hi Kavin
How does this differ from hwstamp_ctl(1)?

It is necessary to manage the Wake-on-LAN clock to turn on the
appropriate blocks for MPD or CFP-based packet matching to work
otherwise we will not be able to reliably match packets during suspend.

Hi David,
This patch series makes the SYSTEMPORT driver request and manage its
main and Wake-on-LAN clocks appropriately.
Florian Fainelli (3):
dt-bindings: net: Document Broadcom SYSTEMPORT clocks
net: systemport: fetch and use clock resources
net: systemport: Manage Wake-on-LAN clock
..
We disable clocks shortly after probing the device to save as much power as
possible in case the interface is never used. When bcm_sysport_open() is
invoked, clocks are enabled, and disabled in bcm_sysport_stop().
A similar scheme is applied to the suspend/resume functions.
Signed-off-by: Florian
The Broadcom SYSTEMPORT adapters require the use of two clocks for
normal operations and during Wake-on-LAN, document those in the binding
document.

Jakub, you suggested/requested that the Qualcomm IPA driver get

working on this a few months ago but didn't finish, and picked

Poorly predicted branches are an even bigger waste.

This series add support for creating VLAN interface over HSR or
PRP interface. Typically industrial networks uses VLAN in
deployment and this capability is needed to support these
networks.
This is tested using two TI AM572x IDK boards connected back
