Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new
ETH_MAX_MTU that is identical to IP_MAX_MTU, but accessible by includes
all ethernet and ethernet-like drivers all have already.
acenic:
- min_mtu = 0, max_mtu = 9000
amazon/ena:
- min_mtu = 128, max_mtu = adapter->max_mtu

mv643xx_eth:
- min_mtu = 64, max_mtu = 9500
mlxsw:
- min_mtu = 0, max_mtu = 65535
- Basically bypassing the core checks, and instead relying on dynamic
checks in the respective switch drivers' ndo_change_mtu functions
ns83820:
- min_mtu = 0
- remove redundant ns83820_change_mtu, only checked for mtu > 1500
netxen:
- min_mtu = 0, max_mtu = 8000 (P2), max_mtu = 9600 (P3)
qlge:
- min_mtu = 1500, max_mtu = 9000
- driver only supports setting mtu to 1500 or 9000, so the core check only
rules out < 1500 and > 9000, qlge_change_mtu still needs to check that
the value is 1500 or 9000
qualcomm/emac:
- min_mtu = 46, max_mtu = 9194
xilinx_axienet:
- min_mtu = 64, max_mtu = 9000

clk_prepare, clk_enable and their counterparts (at least the common clk
ones, but also most others) do check for the clk being NULL anyhow (and
return 0 then), so there is no gain when the caller checks, too.

The patch isolating the u16 writes for pxa assumed all machine_is_*()
calls were removed, and therefore removed the mach-types.h include which
provided them.
Unfortunately 2 machine_is_*() remained in smc91x.c file including
smc91x.h from which the include was removed, triggering the error:
drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_drv_probe’:
drivers/net/ethernet/smsc/smc91x.c:2380:2: error: implicit declaration
of function ‘machine_is_assabet’
[-Werror=implicit-function-declaration]
if (machine_is_assabet() && machine_has_neponset())
This adds back the wrongly removed include.

hardcoded values
The macb driver hardcoded the tx/rx ring sizes. This made it
impossible to change the sizes at run time.
Add tx_ring_size, and rx_ring_size variables to macb object, which
are initilized with default vales during macb_init. Change all
references to RX_RING_SIZE and TX_RING_SIZE to their respective
replacements.

Writes to u16 has a special handling on 3 PXA platforms, where the
hardware wiring forces these writes to be u32 aligned.
This patch isolates this handling for PXA platforms as before, but
enables this "workaround" to be set up dynamically, which will be the
case in device-tree build types.
This patch was tested on 2 PXA platforms : mainstone, which relies on
the workaround, and lubbock, which doesn't.

with leds namespace
Adding led support for phy causes namespace conflicts for some
phy drivers.
The marvel skge driver declared an enum for representing the states of
Link LED Register. The enum contained constant LED_OFF which conflicted
with declartation found in linux/leds.h.
LED_OFF changed to LED_REG_OFF
Also changed LED_ON to LED_REG_ON to avoid possible future conflict and
for consistency.

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).

While handling SPQ ramrod completion, there is a possible race
where driver might not read updated fw return code based on
ramrod completion done. This patch ensures that fw return code
is written first and then completion done flag is updated
using appropriate memory barriers.

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.

Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not
actually performing unicast MAC filtering.
While we're at it - relax a hard-coded limitation that limits each
interface into using at most 15 unicast MAC addresses before turning
promiscuous. Instead utilize the HW resources to their limit.

Due to hardware limitation, when transmitting a geneve-encapsulated
packet with more than 32 bytes worth of geneve options the hardware
would not be able to crack the packet and consider it a regular UDP
packet.
This implements the ndo_features_check() in qede in order to prevent
GSO on said transmitted packets.

Some hypervisors can support MAC hints to their VFs.
Even though we don't have such a hypervisor API in linux, we add
sufficient logic for the VF to be able to receive such hints and
set the mac accordingly - as long as the VF has not been set with
a MAC already.

'is_tcf_mirred_mirror'
These accessors are used in various drivers that support tc offloading,
to detect properties of a given 'tc_action'.
'is_tcf_mirred_redirect' tests that the action is TCA_EGRESS_REDIR.
'is_tcf_mirred_mirror' tests that the action is TCA_EGRESS_MIRROR.
As a prep towards supporting INGRESS redir/mirror, rename these
predicates to reflect their true meaning:
s/is_tcf_mirred_redirect/is_tcf_mirred_egress_redirect/
s/is_tcf_mirred_mirror/is_tcf_mirred_egress_mirror/

The gmac 4.x version has not extended descriptors
(that are available on 3.x instead of).
While initializing the PTP module, the advanced PTP was
enabled in case of extended descriptors. This cannot be
applied for 4.x version where only the hardware capability
register has to show if the feature is present.
Patch also adds some extra netdev_(debug/inof) to better
dump the configuration.
