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") ==================== Signed-off-by: David S.
