e100: min_mtu 68, max_mtu 1500
- remove e100_change_mtu entirely, is identical to old eth_change_mtu,
and no longer serves a purpose. No need to set min_mtu or max_mtu
explicitly, as ether_setup() will already set them to 68 and 1500.
e1000: min_mtu 46, max_mtu 16110
e1000e: min_mtu 68, max_mtu varies based on adapter
fm10k: min_mtu 68, max_mtu 15342
- remove fm10k_change_mtu entirely, does nothing now
i40e: min_mtu 68, max_mtu 9706
i40evf: min_mtu 68, max_mtu 9706
igb: min_mtu 68, max_mtu 9216
- There are two different "max" frame sizes claimed and both checked in
the driver, the larger value wasn't relevant though, so I've set max_mtu
to the smaller of the two values here to retain identical behavior.
igbvf: min_mtu 68, max_mtu 9216
- Same issue as igb duplicated
ixgb: min_mtu 68, max_mtu 16114
- Also remove pointless old == new check, as that's done in dev_set_mtu
ixgbe: min_mtu 68, max_mtu 9710
ixgbevf: min_mtu 68, max_mtu dependent on hardware/firmware
- Some hw can only handle up to max_mtu 1504 on a vf, others 9710

atl2: min_mtu 40, max_mtu 1504
- Remove a few redundant defines that already have equivalents in
if_ether.h.
atl1: min_mtu 42, max_mtu 10218
atl1e: min_mtu 42, max_mtu 8170
atl1c: min_mtu 42, max_mtu 6122/1500
- GbE hardware gets a max_mtu of 6122, slower hardware gets 1500.
alx: min_mtu 34, max_mtu 9256
- Not so sure that minimum MTU number is really what was intended, but
that's what the math actually makes it out to be, due to max_frame
manipulations and comparison in alx_change_mtu, rather than just
comparing new_mtu. (I think 68 was the intended min_mtu value).

The Switches use GPIO lines to indicate interrupts from two of the
switches.
With these interrupts in place, we can make use of the interrupt
controllers within the switch to indicate when the internal PHYs

The PHY interrupts are now handled in a threaded interrupt handler,
which can sleep. The work queue is no longer needed, phy_change() can
be called directly. phy_mac_interrupt() still needs to be safe to call
in interrupt context, so keep the work queue, and use a helper to call
phy_change().

The interrupt lines from PHYs maybe connected to I2C bus expanders, or
from switches on MDIO busses. Such interrupts are sourced from devices
which sleep, so use threaded interrupts. Threaded interrupts require
that the interrupt requester also uses the threaded API. Change the
phylib to use the threaded API, which is backwards compatible with
none-threaded IRQs.

The switch can have up to two interrupt controllers. One of these
contains the interrupts from the integrated PHYs, so is useful to
export. The Marvell PHY driver can then be used in interrupt mode,
rather than polling, speeding up PHY handling and reducing load on the
MDIO bus.

This l3mdev_ops structure is only stored in the l3mdev_ops field of a
net_device structure. This field is declared const, so the l3mdev_ops
structure can be declared as const also. Additionally drop the
__read_mostly annotation.
The semantic patch that adds const is as follows:

// <smpl>

Add a dst_cache to ila_lwt structure. This holds a cached route for the
translated address. In ila_output we now perform a route lookup after
translation and if possible (destination in original route is full 128
bits) we set the dst_cache. Subsequent calls to ila_output can then use
the cache to avoid the route lookup.
This eliminates the need to set the gateway on ILA routes as previously
was being done. Now we can do something like:
./ip route add 3333::2000:0:0:2/128 encap ila 2222:0:0:2 \

Malicious VFs might be caught in several different methods:
- Misusing their bar permission and being blocked by hardware.
- Misusing their fastpath logic and being blocked by firmware.
- Misusing their interaction with their PF via hw-channel,
and being blocked by PF driver.
On the first two items, firmware would indicate to driver that
the VF is to be considered malicious, but would sometime still
allow the VF to communicate with the PF [depending on the exact
nature of the malicious activity done by the VF].
The current existing logic on the PF side lacks handling of such events,
and might allow the PF to perform some incorrect configuration on behalf
of a VF that was previously indicated as malicious.
The new scheme is simple -
Once the PF determines a VF is malicious it would:
a. Ignore any further requests on behalf of the VF-driver.
b. Prevent any configurations initiated by the hyperuser for
the malicious VF, as firmware isn't willing to serve such.
The malicious indication would be cleared upon the VF flr,
after which it would become usable once again.

Whenever a ramrod is being sent for some device configuration,
the driver is going to sleep at least 5ms between each iteration
of polling on the completion of the ramrod.
However, in almost every configuration scenario the firmware
would be able to comply and complete the ramrod in a manner of
several usecs. This is especially important in cases where there
might be a lot of sequential configurations applying to the hardware
[e.g., RoCE], in which case the existing scheme might cause some
visible user delays.
This patch changes the completion scheme - instead of immediately
starting to sleep for a 'long' period, allow the device to quickly
poll on the first iteration after a couple of usecs.

'tcfm_ok_push' specifies whether a mac_len sized push is needed upon
egress to the target device (if action is performed at ingress).
Rename it to 'tcfm_mac_header_xmit' as this is actually an attribute of
the target device (and use a bool instead of int).
This allows to decouple the attribute from the action to be taken.

The "vf_vlan_info" struct ends with a 2 byte struct hole so we have to
memset it to ensure that no stack information is revealed to user space.

We should clear out the padding and unused struct members so that we
don't expose stack information to userspace.

Commit e0d56fdd7342 was a bit aggressive removing l3mdev calls in
the IPv4 stack. If the fib_lookup fails we do not want to drop to
make_route if the oif is an l3mdev device.
Also reverts 19664c6a0009 ("net: l3mdev: Remove netif_index_is_l3_master")
which removed netif_index_is_l3_master.
Fixes: e0d56fdd7342 ("net: l3mdev: remove redundant calls")

The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.
If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.
If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.
Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.
This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,
e.g. phy_error().
