Hardware only support tcp/udp/sctp l4 checksum offload, but
the driver currently tell hardware to do l4 checksum offlad when
l3 is IPv4 or IPv6, which may cause checksumm error.
This patch fixes it by only enabling the l4 offload when l4 is
tcp/udp/sctp.

The HCLGE_RX_PRIV_EN_B is used to tell the firmware whether
to update the specific waterline value, if the is not set,
the firmware will ignore the value.
This patch fixes by setting the HCLGE_RX_PRIV_EN_B even if
the updated value is zero.

Currently, tc related configuration is not setup when the

This patch fixes it by setting the tc related configuration

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.

====================
sock cookie initializers
Recent UDP GSO and SO_TXTIME features added new fields to cookie
structs.
When adding a field, all sites where a struct is initialized have to
be updated, which is a lot of boilerplate. Alternatively, a field can
be initialized selectively, but this is fragile. I introduced a bug
in udp gso where an uninitialized field was read. See also fix commit
("9887cba19978 ip: limit use of gso_size to udp").
Introduce initializers for structs ipcm(6)_cookie and sockc_cookie.
patch 1..3 do exactly this.
patch 4..5 make ipv4 and ipv6 handle cookies the same way and
remove some boilerplate in doing so.
patch 6 removes the udp gso branch that needed the above fix

Now that ipc(6)->gso_size is correctly initialized in all callers of
ip(6)_setup_cork, it is safe to unconditionally pass it to the cork.

skb_shinfo(skb)->tx_flags is derived from sk->sk_tsflags, possibly
after modification by __sock_cmsg_send, by calling sock_tx_timestamp.
The IPv4 and IPv6 paths do this conversion differently. In IPv4, the
individual protocols that support tx timestamps call this function
and store the result in ipc.tx_flags. In IPv6, sock_tx_timestamp is
called in __ip6_append_data.
There is no need to store both tx_flags and ts_flags in the cookie
as one is derived from the other. Convert when setting up the cork
and remove the redundant field. This is similar to IPv6, only have
the conversion happen only once per datagram, in ip(6)_setup_cork.
Also change __ip6_append_data to match __ip_append_data. Only update
tskey if timestamping is enabled with OPT_ID. The SOCK_.. test is
redundant: only valid protocols can have non-zero cork->tx_flags.
After this change the IPv4 and IPv6 logic is the same.

ipcm_cookie includes sockcm_cookie. Do the same for ipcm6_cookie.
This reduces the number of arguments that need to be passed around,
applies ipcm6_init to all cookie fields at once and reduces code
differentiation between ipv4 and ipv6.

If we have an L3 master device, l3mdev_ip_rcv() will steal the skb, but
we were returning NET_RX_SUCCESS from ip_rcv_finish_core() which meant
that ip_list_rcv_finish() would keep it on the list. Instead let's
move the l3mdev_ip_rcv() call into the caller, so that our response to
a steal can be different in the single packet path (return
NET_RX_SUCCESS) and the list path (forget this packet and continue).

Add configuration parameters support
Add configuration parameters setting through devlink.
Each device registers supported configuration parameters table.
Each parameter can be either generic or driver specific.
The user can retrieve data on these parameters by "devlink param show"
command and can set new value to a parameter by "devlink param set"
command.
The parameters can be set in different configuration modes:
runtime - set while driver is running, no reset required.
driverinit - applied while driver initializes, requires restart
driver by devlink reload command.
permanent - written to device's non-volatile memory, hard reset required.
The patches at the end of the patchset introduce few params that are using
the introduced infrastructure on mlx4 and bnxt.
Command examples and output:
pci/0000:81:00.0:
name internal_error_reset type generic
values:
cmode runtime value true
cmode driverinit value true
name max_macs type generic
values:
cmode driverinit value 128
name enable_64b_cqe_eqe type driver-specific
values:
cmode driverinit value true
name enable_4k_uar type driver-specific
values:

The table consists of two generic parameters and two driver-specific

Generic:

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.

mlx4_remove_one().
