This patch adds an optional shared block clock to avoid lockups on
clock gated controllers. Besides the new clock, clock handling for
existing clocks is cleaned up and moved to devm_clk_get. Device
tree binding documentation is updated for the new clocks property.

The different steering modes are global to the device, with DMFS
being introduced after SRIOV was merged. Hence, SRIOV guests running
legacy / older Linux kernels or non-Linux drivers may provide
B0 steering directives when the hypervisor is using DMFS and fail.
Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS.
Use this fact to enable such legacy guests to run by modifying the SRIOV
B0 steering wrapper to translate guest B0 directives to DMFS ones when
the device uses DMFS. The translated B0 rule has to be kept in the
resource tracker as a B0 object to allow for lookup in case of detach.

A pre-step for supporting guests that use B0 steering over a hypervisor
that runs in DMFS (device managed flow steering mode). Add helper function
which allows to translate L2 attachments / detachments provided in B0 mode
to DMFS rules.

Using bool can make code more readable.
Convert uses and tests of int to bool.
This also makes a comparison of tg3->link_up
(itself bool) a bool comparison instead of int.
Reorder stack variable declarations to make
bool fit declaration holes where appropriate.

Normally on driver load, we set the default settings for speed and flow
control. However, if the default setting is not compatible with the current link
state, we would autonegotiate and cause a link flap. To avoid this, we
pull the current advertised settings into the config.
A second scenario is if a user changes the speed/duplex/fc settings when
the interface is down. In this case we must not pull the settings from
the phy and overwrite user settings. We avoid that by checking the
USER_CONFIGURED flag.

This patch and the following two patches add support for link flap avoidance
by maintaining the link on power down. This feature is required for
management capable devices to have the management connection
uninterrupted on driver reload, reboot and interface up/down.
The other pros of this feature are
- It speeds up boot up time by several seconds as DHCP addresses can be
acquired faster.
- It avoids lengthy Spanning Tree delay.
On powerup the hardware brings up the phy with default settings. If the
link is not up, the management software configures the phy to gigabit
and starts autonegotiate. Subsequently, as long as the link is up, the
driver and management refrain from resetting and/or changing any
configuration that the link depends on.
The LNK_FLAP_AVOID setting is an NVRAM user configurable bit and is
disabled by default. If this setting is enabled, we skip powering down
the phy and resetting it.
A second NVRAM setting is 1G_ON_VAUX_OK (off by default). This adds
support for gigabit link speed when device is on auxiliary power.

In tg3_setup_copper_phy(), if autonegotiation is disabled, we need to
relink only if the speed or duplex does not match the configured
setting. If flow control does not match, a relink is not necessary as
flow control is not a PHY setting. Later on, we'll call
tg3_setup_flow_ctrl() to set up the MAC to the desired flow control
settings if we're in full duplex mode.

recently many new supports have been added in the stmmac driver w/o taking care
about where each new field had to be placed inside the private structure for
guaranteeing the best cache usage.
This is what I wanted in the beginning, so this patch reorganizes all the fields
in order to keep adjacent fields for cache effect.
I have also tried to optimize them by using pahole.
V2: do not abuse with ____cacheline_aligned_in_smp and keep fields that
potentially could stay in the same cache-line for better usage in SMP systems.

Remove useless action PHY_READ_EFUSE, PHY_READ_MAC_BYTE, PHY_WRITE_MAC_BYTE,
PHY_WRITE_ERI_WORD. And define the new action PHY_MDIO_CHG.
PHY_MDIO_CHG is used to modify the mdio operation. By the way, the
firmware could support setting mac ocp.

Replace the current settings with rtl_writephy and rtl_readphy.
For the hardware, the settings are same with previous ones. This
make the setting method like the previous chips.

Since of_get_mac_address() is now defined even if CONFIG_OF_NET
is not configured, the ifdef around the code calling it is no longer
necessary and can be removed.
Similar, since of_get_phy_mode() is now defined as dummy function
if OF_NET is not configured, it is no longer necessary to provide
an OF dependent function as front-end. Also, the function depends
on OF_NET, not on OF, so the conditional code was not correct anyway.
Drop the front-end function and call of_get_phy_mode() directly.

Its pretty plainly the result of an skb fragment getting unmapped without having
its initial mapping operation checked for errors. This patch corrects that.
