A devlink port may be for a controller consist of PCI device.
A devlink instance holds ports of two types of controllers.
(1) controller discovered on same system where eswitch resides
This is the case where PCI PF/VF of a controller and devlink eswitch
instance both are located on a single system.
(2) controller located on external host system.
This is the case where a controller is located in one system and its
devlink eswitch ports are located in a different system.
When a devlink eswitch instance serves the devlink ports of both
controllers together, PCI PF/VF numbers may overlap.
Due to this a unique phys_port_name cannot be constructed.
For example in below such system controller-0 and controller-1, each has
PCI PF pf0 whose eswitch ports can be present in controller-0.
These results in phys_port_name as "pf0" for both.
Similar problem exists for VFs and upcoming Sub functions.

Add support to specify the clock provider for the PHY refclk and don't
rely on 'magic' host clock setup. [1] tried to address this by
introducing a flag and fixing the corresponding host. But this commit
breaks the IRQ support since the irq setup during .config_intr() is
thrown away because the reset comes from the side without respecting the
current PHY state within the PHY library state machine. Furthermore the
commit fixed the problem only for FEC based hosts other hosts acting
like the FEC are not covered.
This commit goes the other way around to address the bug fixed by [1].
Instead of resetting the device from the side every time the refclk gets
(re-)enabled it requests and enables the clock till the device gets
removed. Now the PHY library is the only place where the PHY gets reset
to respect the PHY library state machine.

Eric's suggested fix for the previous commit's mentioned race condition
was to simply take the table->lock in wg_index_hashtable_replace(). The
table->lock of the hash table is supposed to protect the bucket heads,
not the entires, but actually, since all the mutator functions are
already taking it, it makes sense to take it too for the test to
hlist_unhashed, as a defense in depth measure, so that it no longer
races with deletions, regardless of what other locks are protecting
individual entries. This is sensible from a performance perspective
because, as Eric pointed out, the case of being unhashed is already the
unlikely case, so this won't add common contention. And comparing
instructions, this basically doesn't make much of a difference other
than pushing and popping %r13, used by the new `bool ret`. More
generally, I like the idea of locking consistency across table mutator
functions, and this might let me rest slightly easier at night.

Eric reported that syzkaller found a race of this variety:
CPU 1 CPU 2
-------------------------------------------|---------------------------------------
wg_index_hashtable_replace(old, ...) |
if (hlist_unhashed(&old->index_hash)) |
| wg_index_hashtable_remove(old)
| hlist_del_init_rcu(&old->index_hash)
| old->index_hash.pprev = NULL
hlist_replace_rcu(&old->index_hash, ...) |
*old->index_hash.pprev |
Syzbot wasn't actually able to reproduce this more than once or create a
reproducer, because the race window between checking "hlist_unhashed" and
calling "hlist_replace_rcu" is just so small. Adding an mdelay(5) or
similar there helps make this demonstrable using this simple script:
#!/bin/bash
set -ex
trap 'kill $pid1; kill $pid2; ip link del wg0; ip link del wg1' EXIT
ip link add wg0 type wireguard
ip link add wg1 type wireguard
wg set wg0 private-key <(wg genkey) listen-port 9999
wg set wg1 private-key <(wg genkey) peer $(wg show wg0 public-key) endpoint 127.0.0.1:9999 persistent-keepalive 1
wg set wg0 peer $(wg show wg1 public-key)
ip link set wg0 up
yes link set wg1 up | ip -force -batch - &
pid1=$!
yes link set wg1 down | ip -force -batch - &
pid2=$!
wait
The fundumental underlying problem is that we permit calls to wg_index_
hashtable_remove(handshake.entry) without requiring the caller to take
the handshake mutex that is intended to protect members of handshake
during mutations. This is consistently the case with calls to wg_index_
hashtable_insert(handshake.entry) and wg_index_hashtable_replace(
handshake.entry), but it's missing from a pertinent callsite of wg_
index_hashtable_remove(handshake.entry). So, this patch makes sure that
mutex is taken.
The original code was a little bit funky though, in the form of:
remove(handshake.entry)
lock(), memzero(handshake.some_members), unlock()
remove(handshake.entry)
The original intention of that double removal pattern outside the lock
appears to be some attempt to prevent insertions that might happen while
locks are dropped during expensive crypto operations, but actually, all
callers of wg_index_hashtable_insert(handshake.entry) take the write
lock and then explicitly check handshake.state, as they should, which
the aforementioned memzero clears, which means an insertion should
already be impossible. And regardless, the original intention was
necessarily racy, since it wasn't guaranteed that something else would
run after the unlock() instead of after the remove(). So, from a
soundness perspective, it seems positive to remove what looks like a
hack at best.
The crash from both syzbot and from the script above is as follows:

back to the VF after hibernation. Note: after we close and re-open the
vmbus channel of the netvsc NIC in netvsc_suspend() and netvsc_resume(),
the data path is implicitly switched to the netvsc NIC. Similarly,
netvsc_suspend() should not call netvsc_unregister_vf(), otherwise the VF
can no longer be used after hibernation.
For mlx4, since the VF network interafce is explicitly destroyed and
re-created during hibernation (see mlx4_suspend()/resume()), hv_netvsc
already explicitly switches the data path from and to the VF automatically
via netvsc_register_vf() and netvsc_unregister_vf(), so mlx4 doesn't need
this fix. Note: mlx4 can still work with the fix because in
netvsc_suspend()/resume() ndev_ctx->vf_netdev is NULL for mlx4.

If the reported PHY capabilities do not include a given FEC mode, don't
attempt to select that FEC mode anyway. If the user tries to set a mode
through ethtool that is not supported, return an error.
The _REQUESTED bits don't appear in the supported caps, but are implied
by the corresponding FEC bits.

Originally there were several implementations of PHY operations for the
several different PHYs used on Falcon boards. But Falcon is now in a
separate driver, and all sfc NICs since then have had MCDI-managed PHYs.
Thus, there is no need to indirect through function pointers in
efx->phy_op; we can simply call the efx_mcdi_phy_* functions directly.
This also hooks up these functions for EF100, which was previously using
the dummy_phy_ops.

dev_close(), by way of ef100_net_stop(), already brings down the filter
table, so there's no need to do it again (which just causes lots of
WARN_ONs).
Similarly, don't bring it up ourselves, as dev_open() -> ef100_net_open()
will do it, and will fail if it's already been brought up.
