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.

When a bnx2x device encounters parity errors, it will not respond to all
SPQ messages. As a result, the shutdown sequence before reset can take
a long time as the ulp drivers (bnx2i/bnx2fc) have to wait for timeout
of all such messages.
To improve this scenario, when bnx2x returns error on the SPQ, we'll send
an immediate response to the ulp drivers to avoid such lengthy timeouts.
Adjust the return code of relevant functions to return error only if
the message cannot be sent on the SPQ so that we'll generate an error
completion to the ulp drivers.

This patch adds the ethtool callbacks necessary to change the rss
indirection table from userspace. Should the number of interrupts
change (e.g. across a close / open call, or through a reset) and
any one of the indirection table values fall out-of-range, the driver
will reset the indirection table to a default layout.

All drivers that support modification of the RX flow hash indirection

call a ethtool_rxfh_indir_default() function.

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.

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.

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.

This is very similar to bnx2x conversion, but simpler since no special
alignement is required, so goal was not to reduce skb truesize.
Using build_skb() reduces cache line misses in the driver, since we
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.

bnx2x uses following formula to compute its rx_buf_sz :
dev->mtu + 2*L1_CACHE_BYTES + 14 + 8 + 8 + 2
Then core network adds NET_SKB_PAD and SKB_DATA_ALIGN(sizeof(struct
skb_shared_info))
Final allocated size for skb head on x86_64 (L1_CACHE_BYTES = 64,
MTU=1500) : 2112 bytes : SLUB/SLAB round this to 4096 bytes.
Since skb truesize is then bigger than SK_MEM_QUANTUM, we have lot of
false sharing because of mem_reclaim in UDP stack.
One possible way to half truesize is to reduce the need by 64 bytes
(2112 -> 2048 bytes)
Instead of allocating a full cache line at the end of packet for
alignment, we can use the fact that skb_shared_info sits at the end of
skb->head, and we can use this room, if we convert bnx2x to new
build_skb() infrastructure.
skb_shared_info will be initialized after hardware finished its
transfert, so we can eventually overwrite the final padding.
Using build_skb() also reduces cache line misses in the driver, since we
use cache hot skb instead of cold ones. Number of in-flight sk_buff
structures is lower, they are recycled while still hot.
Performance results :
(820.000 pps on a rx UDP monothread benchmark, instead of 720.000 pps)

There are valid configurations where Max BW is configured to zero for
some VNs.
Print the message only if debugging is enabled and do not call the
configuration "illegal".
[v2: use DP(), not BNX2X_DBG_ERR(); recommended by Eilon Greenstein.]

stmmac, niu: support uc filtering and yet it propagated
ndo_set_multicast_list
bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set

Uses of pr_cont should be avoided where reasonably possible
because they can be interleaved by other threads and processes.
Coalesce pr_cont uses.
Fix typos, duplicated words and spacing in DP uses caused
by split multi-line formats. Coalesce some of these
split formats. Add missing terminating newlines to DP uses.
