We must first remove the nfnetlink protocol handler when nf_tables module is unloaded -- we don't want userspace to submit new change requests once we've started to tear down nft state. Furthermore, nfnetlink must not call any subsystem function after call_batch returned -EAGAIN. EAGAIN means the subsys mutex was dropped, so its unlikely but possible that nf_tables subsystem was removed due to 'rmmod nf_tables' on another cpu. Therefore, we must abort batch completely and not move on to next part of the batch. Last, we can't invoke ->abort unless we've checked that the subsystem is still registered. Change netns exit path of nf_tables to make sure any incompleted transaction gets removed on exit.

If it fails the namespace is exiting already, and nft core is taking care of cleanup work. We also need to make sure the netdev hook type gets removed before netns ops removal, else notifier might be invoked with device event for a netns where net->nft was never initialised (because pernet ops was removed beforehand).

Once upon a time nfp_cpp_resource_find() took a name parameter,
which could be any user-chosen string. Resources are identified
by a CRC32 hash of a 8 byte string, so we had to pad user input
with zeros to make sure CRC32 gave the correct result.
Since then nfp_cpp_resource_find() was made to operate on allocated
resources only (struct nfp_resource). We kzalloc those so there is
no need to pad the strings and use memcmp.
This avoids a GCC 8 stringop-truncation warning:
In function ‘nfp_cpp_resource_find’,
inlined from ‘nfp_resource_try_acquire’ at .../nfpcore/nfp_resource.c:153:8,

We are gathering software statistics on per-ring basis. .ndo_get_stats64 handler adds the rings up. Unfortunately we are currently only adding up active rings, which means that if user decreases the number of active rings the statistics from deactivated rings will no longer be counted and total interface statistics may go backwards. Always sum all possible rings, the stats are allocated statically for max number of rings, so we don't have to worry about them being removed. We could add the stats up when user changes the ring count, but it seems unnecessary.. Adding up inactive rings will be very quick since no datapath will be touching them.

.ndo_get_phys_port_name was recently extended to support multi-vNIC FWs. These are firmwares which can have more than one vNIC per PF without associated port (e.g. Adaptive Buffer Management FW), therefore we need a way of distinguishing the vNICs. Unfortunately, it's too late to make flower use the same naming. Flower users may depend on .ndo_get_phys_port_name returning -EOPNOTSUPP, for example the name udev gave the PF vNIC was just the bare PCI device-based name before the change, and will have 'nn0' appended after. To ensure flower's vNIC doesn't have phys_port_name attribute, add a flag to vNIC struct and set it in flower code. New projects will not set the flag adhere to the naming scheme from the start.

Patch 2 ensures statistics are correct after users decrease the number of channels/rings. Patch 3 restores phy_port_name behaviour for flower, ndo_get_phy_port_name used to return -EOPNOTSUPP on one of the netdevs, and we need to keep it that way otherwise interface names may change.

The callback model of handling network failover is not suitable
in the current form.
1. It was merged without addressing all the review feedback.
2. It was merged without approval of any of the netvsc maintainers.
3. Design discussion on how to handle PV/VF fallback is still
not complete.
4. IMHO the code model using callbacks is trying to make
something common which isn't.
Revert the netvsc specific changes for now. Does not impact ongoing
development of failover model for virtio.
Revisit this after a simpler library based failover kernel
routines are extracted.

When VF is added, the paravirtual device is already present and may have been moved to another network namespace.

Currently ThunderX NICVF driver has only one ordered workqueue to process such requests for all VFs.
