PF driver doesn't enable tx-switching for all cos queues/clients,
which causes packets drop from PF to VF. Fix this by enabling
tx-switching on all cos queues/clients.

Commit 04f05230c5c13 ("bnx2x: Remove configured vlans as
part of unload sequence."), introduced a regression in driver
that as a part of VF's reload flow, VLANs created on the VF
doesn't get re-configured in hardware as vlan metadata/info
was not getting cleared for the VFs which causes vlan PING to stop.
This patch clears the vlan metadata/info so that VLANs gets
re-configured back in the hardware in VF's reload flow and
PING/traffic continues for VLANs created over the VFs.

Commit 3968d38917eb ("bnx2x: Fix Multi-Cos.") which enabled multi-cos
feature after prolonged time in driver added some regression causing
numerous issues (sudden reboots, tx timeout etc.) reported by customers.
We plan to backout this commit and submit proper fix once we have root
cause of issues reported with this feature enabled.

This patch fixes an issue seen on Power systems with bnx2x which results
in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb
pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons
load in bnx2x_tx_int. Adding a read memory barrier resolves the issue.

Currently bnx2x ptp worker tries to read a register with timestamp
information in case of TX packet timestamping and in case it fails,
the routine reschedules itself indefinitely. This was reported as a
kworker always at 100% of CPU usage, which was narrowed down to be
bnx2x ptp_task.
By following the ioctl handler, we could narrow down the problem to
an NTP tool (chrony) requesting HW timestamping from bnx2x NIC with
RX filter zeroed; this isn't reproducible for example with ptp4l
(from linuxptp) since this tool requests a supported RX filter.
It seems NIC FW timestamp mechanism cannot work well with
RX_FILTER_NONE - driver's PTP filter init routine skips a register
write to the adapter if there's not a supported filter request.
This patch addresses the problem of bnx2x ptp thread's everlasting
reschedule by retrying the register read 10 times; between the read
attempts the thread sleeps for an increasing amount of time starting
in 1ms to give FW some time to perform the timestamping. If it still
fails after all retries, we bail out in order to prevent an unbound
resource consumption from bnx2x.
The patch also adds an ethtool statistic for accounting the skipped
TX timestamp packets and it reduces the priority of timestamping
error messages to prevent log flooding. The code was tested using
both linuxptp and chrony.

Some transceivers may comply with SFF-8472 even though they do not
implement the Digital Diagnostic Monitoring (DDM) interface described in
the spec. The existence of such area is specified by the 6th bit of byte
92, set to 1 if implemented.
Currently, without checking this bit, bnx2x fails trying to read sfp
module's EEPROM with the follow message:
ethtool -m enP5p1s0f1
Cannot get Module EEPROM data: Input/output error
Because it fails to read the additional 256 bytes in which it is assumed
to exist the DDM data.
This issue was noticed using a Mellanox Passive DAC PN 01FT738. The EEPROM
data was confirmed by Mellanox as correct and similar to other Passive
DACs from other manufacturers.

SKB allocation via bnx2x_frag_alloc() is always performed in NAPI
context. Preemptible context passes GFP_KERNEL and bnx2x_frag_alloc()
uses then __get_free_page() for the allocation.
Use napi_alloc_frag() for memory allocation.

mmiowb() is now implied by spin_unlock() on architectures that require
it, so there is no reason to call it from driver code. This patch was
generated using coccinelle:
@mmiowb@
@@
- mmiowb();
and invoked as:
$ for d in drivers include/linux/qed sound; do \
spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done
NOTE: mmiowb() has only ever guaranteed ordering in conjunction with
spin_unlock(). However, pairing each mmiowb() removal in this patch with
the corresponding call to spin_unlock() is not at all trivial, so there
is a small chance that this change may regress any drivers incorrectly
relying on mmiowb() to order MMIO writes between CPUs using lock-free
synchronisation. If you've ended up bisecting to this commit, you can
reintroduce the mmiowb() calls using wmb() instead, which should restore
the old behaviour on all architectures other than some esoteric ia64
systems.

After the previous patch, all the callers of ndo_select_queue()
provide as a 'fallback' argument netdev_pick_tx.
The only exceptions are nested calls to ndo_select_queue(),
which pass down the 'fallback' available in the current scope
- still netdev_pick_tx.
We can drop such argument and replace fallback() invocation with
netdev_pick_tx(). This avoids an indirect call per xmit packet
in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen)
with device drivers implementing such ndo. It also clean the code
a bit.
Tested with ixgbe and CONFIG_FCOE=m
With pktgen using queue xmit:

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable fsz is not necessary, hence
it is removed.
This code was detected with the help of Coccinelle.

for newer hardware. Corresponding function pointer is not

#define CHIP_NUM_57710 0x164e
#define CHIP_NUM_57711 0x164f
#define CHIP_NUM_57711E 0x1650

There will be only one PHC clock per port. PTP should be enabled only on
one PF per port. The change enables PTP functionality on the PF that
initializes the port. The change is useful in multi-function modes e.g.,
NPAR where a port can have more than one PF.

Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.

On some customer setups it was observed that shmem contains a non-zero fip
MAC for 57711 which would lead to enabling of SW FCoE.
Add a software workaround to clear the bad fip mac address if no FCoE
connections are supported.

Driver assigns DMAE channel 0 for FW as part of START_RAMROD command. FW
uses this channel for DMAE operations (e.g., TIME_SYNC implementation).
Driver also uses the same channel 0 for DMAE operations for some of the PFs
(e.g., PF0 on Port0). This could lead to concurrent access to the DMAE
channel by FW and driver which is not legal. Hence need to assign unique
DMAE id for FW.
Currently following DMAE channels are used by the clients,
MFW - OCBB/OCSD functionality uses DMAE channel 14/15
Driver 0-3 and 8-11 (for PF dmae operations)
4 and 12 (for stats requests)
Assigning unique dmae_id '13' to the FW.

stack long ago.

As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.
bnx2x uses NAPI for TX completions, so we better let core
networking stack call the napi->poll() to avoid the capture.

Rx hash/filter table configuration uses rss_conf_obj to configure filters
in the hardware. This object is initialized only when the interface is
brought up.
This patch adds driver changes to configure rss params only when the device
is in opened state. In port disabled case, the config will be cached in the
driver structure which will be applied in the successive load path.
Please consider applying it to 'net' branch.

For most of these calls we can just pass NULL through to the fallback
function as the sb_dev. The only cases where we cannot are the cases where
we might be dealing with either an upper device or a driver that would
have configured things to support an sb_dev itself.
The only driver that has any significant change in this patch set should be
ixgbe as we can drop the redundant functionality that existed in both the
ndo_select_queue function and the fallback function that was passed through
to us.
