Add malicious driver detection to ixgbe driver. The supported devices
are E610 and X550.
Handling MDD events is enabled while VFs are created and turned off
when they are disabled. There is no runtime command to enable or
disable MDD independently.
MDD event is logged when malicious VF driver is detected. For example VF
can try to send incorrect Tx descriptor (TSO on, but length field not
correct). It can be reproduced by manipulating the driver, or using
driver with incorrect descriptor values.
Example log:
"Malicious event on VF 0 tx:128 rx:128"

This reverts commit 565736048b.
According to the commit, it implements a manual AN-37 for some
"troublesome" Juniper MX5 switches. This appears to be a workaround for a
particular switch.
It has been reported that this causes a severe breakage for other switches,
including a Cisco 3560CX-12PD-S.
The code appears to be a workaround for a specific switch which fails to
link in SFI mode. It expects to see AN-37 auto negotiation in order to
link. The Cisco switch is not expecting AN-37 auto negotiation. When the
device starts the manual AN-37, the Cisco switch decides that the port is
confused and stops attempting to link with it. This persists until a power
cycle. A simple driver unload and reload does not resolve the issue, even
if loading with a version of the driver which lacks this workaround.
The authors of the workaround commit have not responded with
clarifications, and the result of the workaround is complete failure to
connect with other switches.
This appears to be a case where the driver can either "correctly" link with
the Juniper MX5 switch, at the cost of bricking the link with the Cisco
switch, or it can behave properly for the Cisco switch, but fail to link
with the Junipir MX5 switch. I do not know enough about the standards
involved to clearly determine whether either switch is at fault or behaving
incorrectly. Nor do I know whether there exists some alternative fix which
corrects behavior with both switches.
Revert the workaround for the Juniper switch.

The MDIO bus speed must be initialized before talking to the PHY the first
time in order to avoid talking to it using a speed that the PHY doesn't
support.
This fixes HW initialization error -17 (IXGBE_ERR_PHY_ADDR_INVALID) on
Denverton CPUs (a.k.a. the Atom C3000 family) on ports with a 10Gb network
plugged in. On those devices, HLREG0[MDCSPD] resets to 1, which combined
with the 10Gb network results in a 24MHz MDIO speed, which is apparently
too fast for the connected PHY. PHY register reads over MDIO bus return
garbage, leading to initialization failure.
Reproduced with Linux kernel 4.19 and 5.15-rc7. Can be reproduced using
the following setup:
* Use an Atom C3000 family system with at least one X552 LAN on the SoC
* Disable PXE or other BIOS network initialization if possible
(the interface must not be initialized before Linux boots)
* Connect a live 10Gb Ethernet cable to an X550 port
* Power cycle (not reset, doesn't always work) the system and boot Linux
* Observe: ixgbe interfaces w/ 10GbE cables plugged in fail with error -17
