b546e46f5c tg3: Fix stats while interface is down
If the tg3 interface is down, the driver will return ethtool stats
uninitialized.  This patch zeroes out the destination stat buffer in
such a case.

c3b5003b62 tg3: Fix single-vector MSI-X code
Kdump kernels leave MSI-X interrupts (as setup by the crashed kernel)
enabled.  However, kdump only enables one CPU in the new environment,
thus causing tg3 to abort MSI-X setup.  When the driver attempts to
enable INTA or MSI interrupt modes on a kdump kernel, interrupt
delivery fails.

This patch attempts to workaround the problem by forcing the driver
to enable a single MSI-X interrupt.  In such a configuration, the
device's multivector interrupt mode must be disabled.

indirection table from userspace.  Should the number of interrupts

will reset the indirection table to a default layout.

2c55a3d08a tg3: Scale back code that modifies MRRS
Tg3 normally gets a performance boost by increasing the PCI Maximum Read
Request Size (MRRS) to 4k.  Unfortunately, this is causing some problems
on particular hardware platforms.  This patch removes all code that
modifies the MRRS except for one case.

As part of a solution to fix an internal FIFO problem on the 5719, the
driver artificially capped the MRRS to 2k for the entire 5719, and later
5720, ASIC revs.  This was overly aggressive and only really needed to
be done for the 5719 A0.  In the spirit of the rest of this patch, the
driver will only reprogram the MRRS for this device if the value exceeds
the 2k cap.

cf9ecf4b63 tg3: Fix TSO CAP for 5704 devs w / ASF enabled
On the earliest TSO capable devices, TSO was accomplished through
firmware.  The TSO cannot coexist with ASF management firmware though.
The tg3 driver determines whether or not ASF is enabled by calling
tg3_get_eeprom_hw_cfg(), which checks a particular bit of NIC memory.
Commit dabc5c670d, entitled "tg3: Move
TSO_CAPABLE assignment", accidentally moved the code that determines
TSO capabilities earlier than the call to tg3_get_eeprom_hw_cfg().  As a
consequence, the driver was attempting to determine TSO capabilities
before it had all the data it needed to make the decision.

This patch fixes the problem by revisiting and reevaluating the decision
after tg3_get_eeprom_hw_cfg() is called.

202ff1c26c tg3: Fix advertisement handling
Commit 28011cf19b (net: Add ethtool to mii advertisment conversion
helpers) added a helper function ethtool_adv_to_mii_100bt() and
tg3_copper_is_advertising_all(), tg3_phy_autoneg_cfg() were
modified to use this.
Before that commit, ethtool to mii advertisement conversion was
done wrt speed, but now pause operation is also taken account.
So, in tg3_copper_is_advertising_all(), below condition becomes
true and this makes link up fails.

	if ((adv_reg & ADVERTISE_ALL) != all_mask)
		return 0;

To fix this add ADVERTISE_ALL bit and operation to cap speed,
and change default advertisement not including ADVERTISED_Pause.

use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are more likely recycled in SLUB caches
while still hot.

For some mutexing purposes, each function is assigned their own
register.  For other cases, each function is assigned its own request
and grant bits of a single register.  For the latter cases, the tg3
driver is incorrectly allowing each function to use the same set of
grant / request bits.  This patch fixes the code so that each function
uses the appropriate bitset.

9e903e0852 net: add skb frag size accessors
To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

5b39de9178 tg3: Add ability to turn off 1shot MSI
In older devices, 1-shot MSI mode had to be enabled by the code.  In
newer devices however, 1-shot MSI mode is enabled by default; code would
be needed to disable it.

Disabling 1-shot MSI mode is useful when debugging.  This patch changes
the code so that the TG3_FLAG_1SHOT_MSI accurately reflects (and
controls) the state of 1-shot MSI mode.
