bnx2x_init_bp() allocates memory with bnx2x_alloc_mem_bp() so if we
fail later in bnx2x_init_one() we need to free this memory
with bnx2x_free_mem_bp() to avoid leakages. E.g. I'm observing memory
leaks reported by kmemleak when a failure (unrelated) happens in
bnx2x_vfpf_acquire().

This patch defines two new GSO definitions SKB_GSO_IPXIP4 and
SKB_GSO_IPXIP6 along with corresponding NETIF_F_GSO_IPXIP4 and
NETIF_F_GSO_IPXIP6. These are used to described IP in IP
tunnel and what the outer protocol is. The inner protocol
can be deduced from other GSO types (e.g. SKB_GSO_TCPV4 and
SKB_GSO_TCPV6). The GSO types of SKB_GSO_IPIP and SKB_GSO_SIT
are removed (these are both instances of SKB_GSO_IPXIP4).
SKB_GSO_IPXIP6 will be used when support for GSO with IP
encapsulation over IPv6 is added.

Not all adapters have FC-NPIV configured. If bnx2fc is used with such an
adapter, driver would read irrelevant data from the the nvram and log
"FC-NPIV table with bad length..." In system logs.
Simply accept that reading '0' as the feature offset in nvram indicates
the feature isn't there and return.

It's not really a bug, but it was odd that bnx2x_eq_int() read the
message data as if it were a cfc_del_event regardless of the event type.
It's cleaner to access only the appropriate member of union event_data
after checking the event opcode.

bnx2x crashes during the initialization of the 8021q module on ppc64.
The bug is a missing conversion from le32 in
bnx2x_handle_classification_eqe() when obtaining the cid value from
struct eth_event_data.
The fields in struct eth_event_data should all be declared as
little-endian and conversions added where missing.

When CONFIG_GENEVE is built as a loadable module, and bnx2x is built-in,
we get this link error:
drivers/net/built-in.o: In function `bnx2x_open':
:(.text+0x33322): undefined reference to `geneve_get_rx_port'
drivers/net/built-in.o: In function `bnx2x_sp_rtnl_task':
:(.text+0x3e632): undefined reference to `geneve_get_rx_port'
This avoids the problem by adding a separate Kconfig symbol named
CONFIG_BNX2X_GENEVE that is only enabled when the code is
reachable from the driver.
This is the same trick that BNX2X does for VXLAN support, and
is similar to how I40E handles both.

The ndo_setup_tc() op was added to support drivers offloading tx
qdiscs however only support for mqprio was ever added. So we
only ever added support for passing the number of traffic classes
to the driver.
This patch generalizes the ndo_setup_tc op so that a handle can
be provided to indicate if the offload is for ingress or egress
or potentially even child qdiscs.

Driver is currently looking at shared information for determining whether
DCBx can be supported for a given port.
On 4-port devices, up-to-date management firmware can support DCBx on
each port of a given engine independently - but that would cause bnx2x to
misinterpert the support and assume DCBx is supported on both.

a regression in regard for vlans for 57710, 57711 adapters -

commit c48f350ff5e7 "bnx2x: Add MFW dump support" added the
bnx2x_update_mfw_dump() function that reads the current time and stores
it in a 32-bit field that gets passed into a buffer in a fixed format.
This is potentially broken when the epoch overflows in 2038, and
otherwise overflows in 2106. As we're trying to avoid uses of
struct timeval for this reason, I noticed the addition of this
function, and tried to rewrite it in a way that is more explicit
about the overflow and that will keep working once we deprecate
struct timeval.
I assume that it is not possible to change the ABI any more, otherwise
we should try to use a 64-bit field for the seconds right away.

Management firmware tells driver in case bandwidth configuration for
a specific function exists, but [regretably] the same field has different
meanings depending on the multi-function mode - it can either be
a percentile value or an actual speed.
For newer multi-function modes current logic is incorrect -
driver understands values as actual speeds instead of percentages,
causing the resulting chip configuration to be incorrect.

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:
- Packets from a VF with pvid configured which were sent with a
different vlan were transmitted instead of being discarded.
- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

The scratchpad is a shared block between all functions of a given device.
Due to HW limitations, we can't properly close its parity notifications
to all functions on legal flows.
E.g., it's possible that while taking a register dump from one function
a parity error would be triggered on other functions.
Today driver doesn't consider this parity as a 'real' parity unless its
being accompanied by additional indications [which would happen in a real
parity scenario]; But it does print notifications for such events in the
system logs.
This eliminates such prints - in case of real parities driver would have
additional indications; But if this is the only signal user will not even
see a parity being logged in the system.

This fixes several issues relating to asymmetric configuration:
1. When user requests to disable TX, the local-device needs to
advertise both PAUSE and ASM_DIR, but to avoid transmitting pause
frames. In the 578xx, it would ignore the TX disable.
2. When user advertises RX-only, ASM_DIR was advertised instead of
PAUSE/ASM_DIR.
3. When changing mode, the advertised PAUSE/ASM_DIR was not cleared
before setting new one, so disabling RX or TX had no impact on the
'advertised' as appeared in the 'ethtool -a' output.

Commit 12a8541d5c82 "bnx2x: Delay during kdump load" added a 5 seconds
delay to bnx2x's probe function in the kdump case to let the firmware
realize the old driver is gone.
The problem with the delay is that it is per-device, so if you have
several bnx2x NICs in NPAR mode, the delays can accumulate to minutes.
Fix it by adjusting the delay so that we do not wait more than
necessary, i.e. no more delaying after 5 seconds of kernel boot time.

In a kdump environment interfaces might be re-loaded without a proper
unload sequence in the previous running kernel.
bnx2x management FW and driver maintains a `pulse' that notifies the FW
that the driver is still up and running.
Driver load on the kdump kernel should be performed only after the pulse
has been out-of-sync long enough for the management FW to identify that
the driver has crashed, on which point it will perform some necessary
cleanup of the HW.
In today's distros kdump loading is quite fast, sometimes too fast for our
FW to get out-of-sync. This patch delays the bnx2x's probe during kdump
to allow a proper re-load on the kdump kernel.

These flags are redundant with dev->features. Remove them.
Just make sure to set dev->features ourselves in bnx2x_set_features()
before performing the reload of the card.

If disable_tpa is set, remove NETIF_F_LRO from hw_features, so ethtool sees
it as "off [fixed]".
Note that setting the NETIF_F_LRO bit in dev->features in the 'else'
branch is not needed, because the bit was already set by
bnx2x_init_dev().
Then the check for disable_tpa in in bnx2x_fix_features() becomes unnecessary.

The TCP conflicts were overlapping changes. In 'net' we added a
READ_ONCE() to the socket cached RX route read, whilst in 'net-next'
Eric Dumazet touched the surrounding code dealing with how mini
sockets are handled.
With USB, it's a case of the same bug fix first going into net-next
and then I cherry picked it back into net.

When IOMM-vtd is active, once main kernel crashes unfinished DMAE transactions
will be blocked, putting the HW in an error state which will cause further
transactions to timeout.
Current employed logic uses wrong macros, causing the first function to be the
only function that cleanups that error state during its probe/load.
This patch allows all the functions to successfully re-load in kdump kernel.

When running in a kdump kernel, it's very likely that due to sync. loss with
management firmware the first PCI function to probe and reach the previous
unload flow would decide it can reset the chip and continue onward. While doing
so, it will only close its own Rx port.
On a 4-port device where 2nd port on engine is a 1g-port, the 2nd port would
allow ingress traffic after the chip is reset [assuming it was active on the
first kernel]. This would later cause a HW attention.
This changes driver flow to close both ports' 1g capabilities during the
previous driver unload flow prior to the chip reset.

It's possible that due to errors [either on PCI or on device itself]
registers reads would fail, returning all-Fs.
This adds a check as early as possible so that driver will not read junk
values and make incorrect probe decisions according to them; instead,
gracefully fail the probe.

To allow drivers to handle the features check for multiple tags,
move the check to ndo_features_check().
As no drivers currently handle multiple tagged TSO, introduce
dflt_features_check() and call it if the driver does not have
ndo_features_check().

Statistics' state-machine in bnx2x driver must be synced with various driver
flows, but its current locking scheme manages to be wasteful [using 2 locks +
additional local variable] and prone to race-conditions at the same time,
as the state-machine and 'action' are being accessed under different locks.
In addition, current 'safe exec' isn't in fact safe, since the only guarantee
it gives is that DMA transactions are over, but ramrods might still be running.
This patch cleans up said logic, leaving us with a single lock for the entire
flow and removing the possible races.
Changes from v2:
- Switched into mutex locking from semaphore locking.
- Release locks on error flows.
Changes from v1:
Failure to acquire lock fails flow instead of printing a warning and
allowing access to the critical section.

Conflicts:
drivers/net/ethernet/emulex/benet/be_main.c
net/core/sysctl_net_core.c
net/ipv4/inet_diag.c
The be_main.c conflict resolution was really tricky. The conflict
hunks generated by GIT were very unhelpful, to say the least. It
split functions in half and moved them around, when the real actual
conflict only existed solely inside of one function, that being
be_map_pci_bars().
So instead, to resolve this, I checked out be_main.c from the top
of net-next, then I applied the be_main.c changes from 'net' since
the last time I merged. And this worked beautifully.
The inet_diag.c and sysctl_net_core.c conflicts were simple
overlapping changes, and were easily to resolve.
