This works fine for XDP and AF_XDP, but if a BPF-prog adjust via
bpf_xdp_adjust_meta() and choose to call XDP_PASS, then igc function
igc_construct_skb_zc() will construct an invalid SKB packet. The

This patch series aims to use new vTcam and Counter API
provided by latest fw version. The advantage of using
this API is the following:

- provides a way to have a rule with desired Tcam size (improves
  Tcam memory utilization).
- batch support for acl counters gathering (improves performance)
- gives more control over HW ACL engine (actions/matches/bindings)
  to be able to support more features in the future driver
  versions

Note: the feature set left the same as was before this patch.

We have VLAN PTP support(via get_ts_info) on kernel, and bond support(by
getting active interface via netlink message) on userspace tool linuxptp.
But there are always some users who want to use PTP with VLAN over bond,
which is not able to do with the current implementation.

This patch passed get_ts_info and SIOC[SG]HWTSTAMP ioctl to active device
with bond mode active-backup/tlb/alb. With this users could get kernel native

dwmac-qcom-ethqos currently exposes a mechanism to dump rgmii registers
after the 'stmmac_dvr_probe()' returns. However with commit
5ec55823 ("net: stmmac: add clocks management for gmac driver"),
we now let 'pm_runtime_put()' disable the clocks before returning from
'stmmac_dvr_probe()'.

This causes a crash when 'rgmii_dump()' register dumps are enabled,
as the clocks are already off.

Since other dwmac drivers (possible future users as well) might
require a similar register dump feature, introduce a platform level
callback to allow the same.

This fixes the crash noticed while enabling rgmii_dump() dumps in
dwmac-qcom-ethqos driver as well. It also allows future changes
to keep a invoking the register dump callback from the correct
place inside 'stmmac_dvr_probe()'.
