Since we can't reliably track the short name changes just assume that we
had a change whenever there's a pending mgmt command. In the worst case
we just get one unnecessary name_changed signal.

Whenever we update the local device name the EIR data also needs to be
updated to reflect this. The update_eir() function in mgmt.c depends on
hdev->dev_name to be up to date so the patch also makes sure that the

For DSS clock domain to transition from idle to active state. It's necessary
to enable the optional clock DSS_FCLK before we enable the module using the
MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register.
This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led
to DSS clock domain not getting out of idle when pm_runtime_get_sync() was
called for hdmi's platform device.
Since the clock domain failed to change it's state to active, the hwmod code
disables any clocks it had enabled before for this hwmod. This led to the clock
'dss_48mhz_clk' gettind disabled.
When hdmi's runtime_resume() op is called, the call to dss_runtime_get()
correctly enables the DSS clock domain this time. However, the clock
'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was
disabled previously, the driver fails when it tries to enable HDMI's PHY.
Fix this for now by ensuring that dss_runtime_get() is called before we call
pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would
be to modify the DSS related hwmod's mainclks, and also some changes in how
opt clocks are handled in the DSS driver.
This fixes the issue of HDMI not working when it's the default display. The
issue is not seen if any other display is already enabled as the first display
would have correctly enabled the DSS clockdomain.

This patch seeks to clean up the timer related code. It begins by
moving one-time timer setup code from tg3_open() to tg3_init_one().
It then creates a function that encapsulates the code needed to start
the timer. A tg3_timer_stop() function was added for parity. Finally,
this patch moves all the timer functions to a more suitable location.

If an error happens in the tx completion thread, tg3_reset_task will be
scheduled and TX_RECOVERY_PENDING will be set. The TX_RECOVERY_PENDING
flag causes tg3_poll[_msix] to return early before doing much of its
work. Tg3_reset_task() gets canceled when the configuration of the
device is changing, which always results in a chip reset. When this
happens, the TX_RECOVERY_PENDING flag may be left set, which would
unnecessarily hinder tg3_poll from doing work. This patch fixes the
problem.

tg3_phy_copper_begin() has code that configures the link

interface. This patch removes the dead code.

The tg3 driver tried to detect link changes by comparing the tg3 local
active_speed member with SPEED_UNKNOWN (or formerly SPEED_INVALID).
This check is not correct, since phylib will never set its speed member
to either of these two values. The code only appeared to work because
tg3 initializes active_speed to SPEED_INVALID during tg3_init_one. This
patch introduces a new "old_link" tg3 member and then compares the
phy_device's link member against it to detect link state changes.

We have a very simple way of allocating buffer table entries to

efx_vfdi_set_status_page() validates the peer page count by
calculating the size of a request containing that many addresses and
comparing that with the maximum valid request size (4KB). The
calculation involves a multiplication that may overflow on a 32-bit
system.
We use kcalloc() to allocate memory to store the addresses; that also
does a multiplication and it does check for integer overflow, so any
values larger than 0x1fffffff will be rejected. However, values in
the range [0x1fffffffc, 0x1fffffff] pass boh tests and result in an
attempt to allocate nearly 4GB on the heap. This should be rejected
rather quickly as it's obviously impossible on a 32-bit system, and
indeed the maximum possible heap allocation is 32MB. Still, let's
make absolutely sure by fixing the initial validation.

This requirement was meant to be implied in the name 'status page'.
One out-of-tree VF driver allocates a buffer using the structure size
and not a full page - hence the current odd specification - but in
practice that allocation will be padded and aligned to at least 4KB.
Therefore, we can specify this and have the option to extend the
structure up to 4KB without worrying about VF drivers using odd-shaped
buffers.
