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.

Until interface is up [and assuming ringparams weren't explicitly
configured] when queried for the size of its rings bnx2x would
claim they're the maximal size by default.
That is incorrect as by default the maximal number of buffers would
be equally divided between the various rx rings.
This prevents the user from actually setting the number of elements
on each rx ring to be of maximal size prior to transitioning the
interface into up state.
To fix this, make a rough estimation about the number of buffers.
It wouldn't always be accurate, but it would be much better than
current estimation and would allow users to increase number of
buffers during early initialization of the interface.

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().

Function bnxt_hwrm_stat_ctx_alloc() always returns 0, even if the call
to _hwrm_send_message() fails. It may be better to propagate the errors

__bcmgenet_tx_reclaim() and bcmgenet_free_rx_buffers() are not using the
same struct device during unmap that was used for the map operation,
which makes DMA-API debugging warn about it. Fix this by always using
&priv->pdev->dev throughout the driver, using an identical device
reference for all map/unmap calls.

When busy polling while a link is down (during a link-flap test), TX
timeouts were observed as well as the following messages in the ring
buffer:
bnxt_en 0008:01:00.2 enP8p1s0f2d2: Resp cmpl intr err msg: 0x51
bnxt_en 0008:01:00.2 enP8p1s0f2d2: hwrm_ring_free tx failed. rc:-1

bnxt_en 0008:01:00.2 enP8p1s0f2d2: hwrm_ring_free rx failed. rc:-1
These were resolved by checking for link status and returning if link

Knowing that:
#define TUNNEL_DST_PORT_FREE_REQ_TUNNEL_TYPE_VXLAN (0x1UL << 0)
#define TUNNEL_DST_PORT_FREE_REQ_TUNNEL_TYPE_GENEVE (0x5UL << 0)
and that 'bnxt_hwrm_tunnel_dst_port_alloc()' is only called with one of
these 2 constants, the TUNNEL_DST_PORT_ALLOC_REQ_TUNNEL_TYPE_GENEVE can not

When people build bnx2 driver into kernel, it will fail to detect

initramfs has not been uncompressed yet during do_initcalls. So
revert commit 3e1be7a and work out a new way in the later patch.

If the physical link is down and the VF virtual link is set to "enable",
the current code does not always work. If the link is down but the
cable is attached, the firmware returns LINK_SIGNAL instead of
NO_LINK. The current code is treating LINK_SIGNAL as link up.
The fix is to treat link as down when the link_status != LINK.

Current bgmac code initializes some DMA settings in the receive control
register for some hardware and then immediately clears those settings.
Not clearing those settings results in ~420Mbps *improvement* in
throughput; this system can now receive frames at line-rate on Broadcom
5871x hardware compared to ~520Mbps today. I also tested a few other
values but found there to be no discernible difference in CPU
utilization even if burst size and prefetching values are different.
On the hardware tested there was no need to keep the code that cleared
all but bits 16-17, but since there is a wide variety of hardware that
used this driver (I did not look at all hardware docs for hardware using
this IP block), I find it wise to move this call up and clear bits just
after reading the default value from the hardware rather than completely
removing it.
This is a good candidate for -stable >=3.14 since that is when the code
that was supposed to improve performance (but did not) was introduced.

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.

gcc found a reference to an uninitialized variable in the error handling
of bcm_enet_open, introduced by a recent cleanup:
drivers/net/ethernet/broadcom/bcm63xx_enet.c: In function 'bcm_enet_open'
drivers/net/ethernet/broadcom/bcm63xx_enet.c:1129:2: warning: 'phydev' may be used uninitialized in this function [-Wmaybe-uninitialized]
This makes the use of that variable conditional, so we only reference it
here after it has been used before. Unlike my normal patches, I have not
build-tested this one, as I don't currently have mips test in my
randconfig setup.

While the driver is probing the adapter, an error may occur before the
netdev structure is allocated and attached to pci_dev. In this case,
not only netdev isn't available, but the tg3 private structure is also
not available as it is just math from the NULL pointer, so dereferences
must be skipped.

valid, this code executes fine
- second time from bcmgenet_mii_probe(), through the normal
phy_init_hw() call (which arguably could be optimized out)
Everything is fine in that case. With commit 62469c76007e, we would have
the following scenario to happen after an ifconfig down then up
sequence:
- bcmgenet_close() calls phy_disonnect() which makes dev->phydev become
NULL
- when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from

We get 1 warning when building kernel with W=1:
drivers/net/ethernet/broadcom/genet/bcmgenet.c:2763:5: warning: no previous prototype for 'bcmgenet_hfb_add_filter' [-Wmissing-prototypes]
In fact, this function is implemented in
drivers/net/ethernet/broadcom/genet/bcmgenet.c, but be called
by no one, thus can be removed.
So this patch removes the unused functions.

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.
For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
Set vf vlan protocol 802.1ad:
ip link set eth0 vf 1 vlan 100 proto 802.1ad
Set vf to VST (802.1Q) mode:
ip link set eth0 vf 1 vlan 100 proto 802.1Q
Or by omitting the new parameter
ip link set eth0 vf 1 vlan 100

bnxt_hwrm_fw_set_time() now returns -EOPNOTSUPP when built for kernel
without RTC_LIB. Setting the firmware time is not critical to the
successful completion of the firmware update process.

The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the
one contained in struct net_device.

The VF link state can be changed via the 'ip link set' cmd.
Currently, the new link state does not take effect immediately.
The fix is for the PF to send a link change async event to the
designated VF after a VF link state change. This async event will
trigger the VF to update the link status.

After generating the random MAC address for VF, call the firmware to
approve it. This step serves 2 purposes. Some hypervisor (e.g. ESX)
wants to approve the MAC address. 2nd, the call will setup the
proper forwarding database in the internal switch.
We need to unlock the hwrm_cmd_lock mutex before calling bnxt_approve_mac().
We can do that because we are at the end of the function and all the
previous firmware response data has been copied.

Re-arrange the code so that the generation of the random MAC address for
the VF is at the end of the function. The next patch will add one more step
to call bnxt_approve_mac() to get the firmware to approve the random MAC
address.

The existing code is inconsistent in reporting and accepting the combined
channel count. bnxt_get_channels() reports maximum combined as the
maximum rx count. bnxt_set_channels() accepts combined count that
cannot be bigger than max rx or max tx.
For example, if max rx = 2 and max tx = 1, we report max supported
combined to be 2. But if the user tries to set combined to 2, it will
fail because 2 is bigger than max tx which is 1.
Fix the code to be consistent. Max allowed combined = max(max_rx, max_tx).
We will accept a combined channel count <= max(max_rx, max_tx).

Using Ethtool flashdev command, entire NVM package (*.pkg) files
may now be staged into the "update" area of the NVM and subsequently
verified and installed by the firmware using the newly introduced
command: NVM_INSTALL_UPDATE.
We also introduce use of the new firmware command FW_SET_TIME so that the
NVM-resident package installation log contains valid time-stamps.

Remove "Single-port/Dual-port" from the device names. Dual-port devices
will appear as 2 separate devices, so no need to call each a dual-port
device. Use a more generic name for VF devices belonging to the same
chip fanmily. Add some remaining NPAR device IDs.
