devm_ioremap_resource() provides its own error messages so all explicit

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.

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.
