Hi Dave,
This patchset introduces two features to the ConnectX-4 driver: Patch 8/8
("Support physical port counters") exposes some hardware counters through
ethtool. Rest of the patches are preparation and usage of what we call
light-weight netdev open/close. Some flows that used to be in the ndo_open/stop
are moved to the PCI probe/remove flows - i.e. we will make the netdev
open/close operations more "light-weight".
The benefits of this change are:
1) Reduce the execution time of the stop/open operations.
2) Avoid saving SW shadows of resource configurations that must
persist through stop/open operations (e.g flow table steering
rules), and avoid deleting/applying them from/to the device upon
netdev stop/open.
3) Avoid synchronizing threads that access those resources with the
netdev stop/open threads.
Instead of create/destroy the resource during netdev open/stop, This patchset
changes the behavior such that upon netdev stop, traffic is redirected to a
"Drop RQ" (a RQ that silently drops, at the NIC HW level all incoming traffic).
After redirecting the traffic, RX/TX software resources could be destroyed.
During netdev open, the RX/TX rings are created and traffic is redirected to
the RX rings.
Patchset was applied and tested over commit ba7591d ("ebpf: add skb->hash to
offset map for usage in {cls, act}_bpf or filters")
Thanks,
Amir
