From: Hamdan Igbaria <hamdani@mellanox.com>
Use kernel function to calculate crc32 Instead of dr implementation
since it has the same algorithm "slice by 8".
Fixes: 26d688e33f88 ("net/mlx5: DR, Add Steering entry (STE) utilities")

From: Igor Leshenko <igorle@mellanox.com>
Not all mlx5 cards with FPGA device use it for network processing.
mlx5_core driver configures network connection to FPGA device
for all mlx5 cards with installed FPGA. If FPGA is not a part of
network path, driver crashes in this case
Check FPGA name in function mlx5_fpga_device_start() and continue
integrate FPGA into packets flow only for dedicated cards.
Currently there are Newton and Edison cards.

Currently, mlx5 tc layer doesn't verify that rule has at least one forward
or drop action which leads to following firmware syndrome when user tries
to offload such action:
[ 1824.860501] mlx5_core 0000:81:00.0: mlx5_cmd_check:753:(pid 29458): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0x144b7a)
Add check at the end of parse_tc_fdb_actions() that verifies that resulting
attribute has action fwd or drop flag set.

FTE memory allocation using alloc_fte() doesn't have any dependency
on the flow group.
Hence, do not hold flow group lock while performing alloc_fte().
This helps to reduce contention of flow group lock.

From: Parav Pandit <parav@mellanox.com>
During connection tracking offloads with high number of connections,
(40K connections per second), flow table group lock contention is
observed.
To improve the performance by reducing lock contention, lockless
FTE read lookup is performed as described below.
Each flow table entry is refcounted.
Flow table entry is removed when refcount drops to zero.
rhash table allows rcu protected lookup.
Each hash table entry insertion and removal is write lock protected.
Hence, it is possible to perform lockless lookup in rhash table using
following scheme.
(a) Guard FTE entry lookup per group using rcu read lock.
(b) Before freeing the FTE entry, wait for all readers to finish
accessing the FTE.
Below example of one reader and write in parallel racing, shows
protection in effect with rcu lock.
lookup_fte_locked()
rcu_read_lock();
search_hash_table()
existing_flow_group_write_lock();
tree_put_node(fte)
drop_ref_cnt(fte)
del_sw_fte(fte)
del_hash_table_entry();
call_rcu();
existing_flow_group_write_unlock();
get_ref_cnt(fte) fails
rcu_read_unlock();
rcu grace period();

Add support for rewriting of DSCP part of ToS field.
Next commands, for example, can be used to offload rewrite action:
OVS:
$ ovs-ofctl add-flow ovs-sriov "ip, in_port=REP, \
actions=mod_nw_tos:68, output:NIC"
iproute2 (used retain mask, as tc command rewrite whole ToS field):
$ tc filter add dev REP ingress protocol ip prio 1 flower skip_sw \
ip_proto icmp action pedit munge ip tos set 68 retain 0xfc pipe \
action mirred egress redirect dev NIC

From: Alex Vesker <valex@mellanox.com>
Until now SW steering supported matchers that are IPv4 and IPv6.
The limitation was mixed matchers in which the outer header IP version
was different from the inner header IP version.
To support the mixed matcher we create all the possible ste_builder
combinations, once we create a rule we select the correct one to
be used for rule creation.
