Problem:
In vxlan_newlink, a default fdb entry is added before register_netdev.
The default fdb creation function also notifies user-space of the
fdb entry on the vxlan device which user-space does not know about yet.
(RTM_NEWNEIGH goes before RTM_NEWLINK for the same ifindex).
This patch fixes the user-space netlink notification ordering issue
with the following changes:
- decouple fdb notify from fdb create.
- Move fdb notify after register_netdev.
- Call rtnl_configure_link in vxlan newlink handler to notify
userspace about the newlink before fdb notify and
hence avoiding the user-space race.

- Add new vxlan_fdb_alloc helper
- rename existing vxlan_fdb_create into vxlan_fdb_update:
because it really creates or updates an existing
fdb entry
- move new fdb creation into a separate vxlan_fdb_create
Main motivation for this change is to introduce the ability
to decouple vxlan fdb creation and notify, used in a later patch.

When CONFIG_BRIDGE_VLAN_FILTERING is disabled, gcc correctly points out
that the 'vid' variable is uninitialized whenever br_vlan_get_pvid
returns an error:

drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:6881:6: error: 'vid' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This changes the condition check to always return -EINVAL here,

t4_get_flash_params() fails in a fatal fashion if the FLASH part isn't
one of the recognized parts. But this leads to desperate efforts to update
drivers when various FLASH parts which we are using suddenly become
unavailable and we need to substitute new FLASH parts. This has lead to
more than one Customer Field Emergency when a Customer has an old driver
and suddenly can't use newly shipped adapters.
This commit fixes this by simply assuming that the FLASH part is 4MB in
size if it can't be identified. Note that all Chelsio adapters will have
flash parts which are at least 4MB in size.

Pre-1.7.2 NIC firmware does not support (and does not respond to) the "get
speed" command which is sent by the 1.7.2 driver (for CN23XX-225 cards
only) during modprobe. Due to a bug in older firmware (with respect to
unknown commands), this unsupported command causes a cascade of errors that
ends in a kernel panic.
Fix it by making the sending of the "get speed" command conditional on the
firmware version.

The change fixes sleep in atomic context bug, which is encountered
every time when link settings are changed by ethtool.
Since commit 35b5f6b1a82b ("PHYLIB: Locking fixes for PHY I/O
potentially sleeping") phy_start_aneg() function utilizes a mutex
to serialize changes to phy state, however that helper function is
called in atomic context under a grabbed spinlock, because
phy_start_aneg() is called by phy_ethtool_ksettings_set() and by
replaced phy_ethtool_sset() helpers from phylib.
Now duplex mode setting is enforced in ravb_adjust_link() only, also
now RX/TX is disabled when link is put down or modifications to E-MAC
registers ECMR and GECMR are expected for both cases of checked and
ignored link status pin state from E-MAC interrupt handler.

NFP doesn't have integer divide instruction, this patch use reciprocal
algorithm (the basic one, reciprocal_div) to emulate it.
For each u32 divide, we would need 11 instructions to finish the operation.
7 (for multiplication) + 4 (various ALUs) = 11
Given NFP only supports multiplication no bigger than u32, we'd require
divisor and dividend no bigger than that as well.
Also eBPF doesn't support signed divide and has enforced this on C language
level by failing compilation. However LLVM assembler hasn't enforced this,
so it is possible for negative constant to leak in as a BPF_K operand
through assembly code, we reject such cases as well.

NFP supports u16 and u32 multiplication. Multiplication is done 8-bits per
step, therefore we need 2 steps for u16 and 4 steps for u32.
We also need one start instruction to initialize the sequence and one or
two instructions to fetch the result depending on either you need the high
halve of u32 multiplication.
For ALU64, if either operand is beyond u32's value range, we reject it. One
thing to note, if the source operand is BPF_K, then we need to check "imm"
field directly, and we'd reject it if it is negative. Because for ALU64,
"imm" (with s32 type) is expected to be sign extended to s64 which NFP mul
doesn't support. For ALU32, it is fine for "imm" be negative though,
because the result is 32-bits and here is no difference on the low halve
of result for signed/unsigned mul, so we will get correct result.

Create initial parameters table for mlx4.
The table consists of two generic parameters and two driver-specific
parameters.
Generic:
internal_err_reset - Enable reset device on internal errors. This
parameter can be configured on mlx4 either on runtime or during driver
initialization.
max_macs - Max number of MACs per ETH port. For mlx4 this parameter
value range is between 1 and 128. This parameter can be configured on
mlx4 only during driver initialization.
Driver specific:
enable_64b_cqe_eqe - Enable 64 byte CQEs/EQEs when the FW supports it.
This parameter can be configured on mlx4 only during driver
initialization.
enable_4k_uar - Enable using 4K UAR. This parameter can be configured on
mlx4 only during driver initialization.
Register the parameters table on mlx4_init_one() and unregister on
mlx4_remove_one().

Variable channel is being assigned but is never used hence it is
redundant and can be removed.
Cleans up two clang warnings:
warning: variable 'channel' set but not used [-Wunused-but-set-variable]

Variables my_epid and max_epid are currently assigned and not being
used - however, I suspect they were intended to be used in the for-loops
to reduce the dereferencing of hw. Replace hw->my_epid and hw->max_epid
with these variables.
Cleans up clang warnings:
warning: variable 'my_epid' set but not used [-Wunused-but-set-variable]
variable 'max_epid' set but not used [-Wunused-but-set-variable]
