When mc configuration changes bnx2x_config_mcast() can return 0 for
success, negative for failure and positive for benign reason preventing
its immediate work, e.g., when the command awaits the completion of
a previously sent command.
When removing all configured macs on a 578xx adapter, if a positive
value would be returned driver would errneously log it as an error.

VFs are currently missing the VLAN filtering feature, because we were

It is possible to crash the kernel by accessing a PTP device while its
associated bnx2x interface is down. Before the interface is brought up,
the timecounter is not initialized, so accessing it results in NULL
dereference.
Fix it by checking if the interface is up.
Use -ENETDOWN as the error code when the interface is down.
-EFAULT in bnx2x_ptp_adjfreq() did not seem right.

Only the 578xx adapters are capable of configuring UDP ports for
the purpose of tunnelling - doing the same on 577xx might lead to
a firmware assertion.
We're already not claiming support for any related feature for such
devices, but we also need to prevent the configuration of the UDP
ports to the device in this case.

Macro BNX2X_ALLOC_AND_SET(arr, lbl, func) calls kmalloc() to allocate
memory, and jumps to label "lbl" if the allocation fails. Label "lbl"
first cleans memory and then returns variable rc. Before calling the
macro, the value of variable rc is 0. Because 0 means no error, the
callers of bnx2x_init_firmware() may be misled. This patch fixes the bug,
assigning "-ENOMEM" to rc before calling macro NX2X_ALLOC_AND_SET().

Time Sync (PTP) implementation uses the divisor/shift value for converting
the clock ticks to nanoseconds. Driver currently defines shift value as 1,
this results in the nanoseconds value to be calculated as half the actual
value. Hence the user application fails to synchronize the device clock
value with the PTP master device clock. Need to use the 'shift' value of 0.

When PCI error is detected, in some architectures (like PowerPC) a slot
reset is performed - the driver's error handlers are in charge of "disable"
device before the reset, and re-enable it after a successful slot reset.
There are two cases though that another path is taken on the code: if the
slot reset is not successful or if too many errors already happened in the
specific adapter (meaning that possibly the device is experiencing a HW
failure that slot reset is not able to solve), the core PCI error mechanism
(called EEH in PowerPC) will remove the adapter from the system, since it
will consider this as a permanent failure on device. In this case, a path
is taken that leads to bnx2x_chip_cleanup() calling bnx2x_reset_hw(), which
then tries to perform a HW reset on chip. This reset won't succeed since
the HW is in a fault state, which can be seen by multiple messages on
kernel log like below:
bnx2x: [bnx2x_issue_dmae_with_comp:552(eth1)]DMAE timeout!
bnx2x: [bnx2x_write_dmae:600(eth1)]DMAE returned failure -1
After some time, the PCI error mechanism gives up on waiting the driver's
correct removal procedure and forcibly remove the adapter from the system.
We can see soft lockup while core PCI error mechanism is waiting for driver
to accomplish the right removal process.
This patch adds a verification to avoid a chip reset whenever the function
is in PCI error state - since this case is only reached when we have a
device being removed because of a permanent failure, the HW chip reset is
not expected to work fine neither is necessary.
Also, as a minor improvement in error path, we avoid the MCP information dump
in case of non-recoverable PCI error (when adapter is about to be removed),
since it will certainly fail.

When ndo_set_rx_mode() is called for bnx2x, as part of process of
configuring the new MAC address filters [both unicast & multicast]
driver begins by flushing the existing configuration and then iterating
over the network device's list of addresses and configures those instead.
This has the side-effect of creating a short gap where traffic wouldn't
be properly classified, as no filters are configured in HW.
While for unicasts this is rather insignificant [as unicast MACs don't
frequently change while interface is actually running],
for multicast traffic it does pose an issue as there are multicast-based
networks where new multicast groups would constantly be removed and
added.
This patch tries to remedy this [at least for the newer adapters] -
Instead of flushing & reconfiguring all existing multicast filters,
the driver would instead create the approximate hash match that would
result from the required filters. It would then compare it against the
currently configured approximate hash match, and only add and remove the
delta between those.

Since implementing VLAN filtering in commit 05cc5a39ddb74
("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while
the interface is down:
# ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10
RTNETLINK answers: Bad address
and in dmesg (with bnx2x.debug=0x20):
bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN
configuration the interface is down
Other drivers have no problem with this.
Fix this peculiar behavior in the following way:
- Accept requests to add/kill VID regardless of the device state.
Maintain the requested list of VIDs in the bp->vlan_reg list.
- If the device is up, try to configure the VID list into the hardware.
If we run out of VLAN credits or encounter a failure configuring an
entry, fall back to accepting all VLANs.
If we successfully configure all entries from the list, turn the
fallback off.
- Use the same code for reconfiguring VLANs during NIC load.

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':

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.

On 4-port devices, up-to-date management firmware can support DCBx on

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.

- Packets from a VF with pvid configured which were sent with a

- 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.

As bnx2x_init_ptp() is only called if bp->flags contains PTP_SUPPORTED,
we also need to guard bnx2x_stop_ptp() with same condition, otherwise
ptp_task workqueue is not initialized and kernel barfs on
cancel_work_sync()

20g-capable devices are not configured properly for self-test, using
10g as their speed which cause the link indication to remain down and
fail the internal loopback test.

There's a bug in today's driver where VF requests to add/remove MAC filters
always reach the Hypervisor as add requests.
This prevents the VF from changing its MAC address, as it cannot remove the
previously configured MAC and runs out of MAC credits.

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.
