net/mlx5e: Consider geneve_opts for encap contexts
Current algorithm for encap keys is legacy from initial vxlan implementation and doesn't take into account all possible fields of a tunnel. For example, for a Geneve tunnel, which may have additional TLV options, they are ignored when comparing encap keys and a rule can be attached to an incorrect encap entry.
Fix that by introducing encap_info_equal() operation in struct mlx5e_tc_tunnel. Geneve tunnel type uses custom implementation, which extends generic algorithm and considers options if they are set.

This patch
flow_dissector: Parse multiple MPLS Label Stack Entries
The current MPLS dissector only parses the first MPLS Label Stack Entry (second LSE can be parsed too, but only to set a key_id).
This patch adds the possibility to parse several LSEs by making __skb_flow_dissect_mpls() return FLOW_DISSECT_RET_PROTO_AGAIN as long as the Bottom Of Stack bit hasn't been seen, up to a maximum of FLOW_DIS_MPLS_MAX entries.
FLOW_DIS_MPLS_MAX is arbitrarily set to 7. This should be enough for many practical purposes, without wasting too much space.
To record the parsed values, flow_dissector_key_mpls is modified to store an array of stack entries, instead of just the values of the first one. A bit field, "used_lses", is also added to keep track of the LSEs that have been set. The objective is to avoid defining a new FLOW_DISSECTOR_KEY_MPLS_XX for each level of the MPLS stack.
TC flower is adapted for the new struct flow_dissector_key_mpls layout. Matching on several MPLS Label Stack Entries will be added in the next patch.
The NFP and MLX5 drivers are also adapted: nfp_flower_compile_mac() and mlx5's parse_tunnel() now verify that the rule only uses the first LSE and fail if it doesn't.
Finally, the behaviour of the FLOW_DISSECTOR_KEY_MPLS_ENTROPY key is slightly modified. Instead of recording the first Entropy Label, it now records the last one. This shouldn't have any consequences since there doesn't seem to have any user of FLOW_DISSECTOR_KEY_MPLS_ENTROPY in the tree. We'd probably better do a hash of all parsed MPLS labels instead (excluding reserved labels) anyway. That'd give better entropy and would probably also simplify the code. But that's not the purpose of this patch, so I'm keeping that as a future possible improvement.

net/mlx5e: Add support for hw encapsulation of MPLS over UDP
MPLS over UDP is supported by adding a rule on a representor net device which does tunnel_key set, push mpls and forward to a baredup device. At the hardware level we use a packet_reformat_context object to do the encapsulation of the packet.
The resulting packet looks as follows (left side transmitted first): outer L2 | outer IP | UDP | MPLS | inner L3 and data |
Example usage: tc filter add dev $rep0 protocol ip prio 1 root flower skip_sw \ action tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 id 555 \ dst_port 6635 tos 4 ttl 6 csum action mpls push protocol 0x8847 \ label 555 tc 3 action mirred egress redirect dev bareudp0
This is how the filter is shown with tc filter show: tc filter show dev enp59s0f0_0 ingress filter protocol ip pref 1 flower chain 0 filter protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 skip_sw in_hw in_hw_count 1 action order 1: tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 key_id 555 dst_port 6635 csum tos 0x4 ttl 6 pipe index 1 ref 1 bind 1
action order 2: mpls push protocol mpls_uc label 555 tc 3 ttl 255 pipe index 1 ref 1 bind 1
action order 3: mirred (Egress Redirect to device bareudp0) stolen index 1 ref 1 bind 1

net/mlx5e: Add support for hw encapsulation of MPLS over UDP MPLS over UDP is supported by adding a rule on a representor net device which does tunnel_key set, push mpls and forward to a baredup device. At the hardware level we use a packet_reformat_context object to do the encapsulation of the packet. The resulting packet looks as follows (left side transmitted first): outer L2 | outer IP | UDP | MPLS | inner L3 and data | Example usage: tc filter add dev $rep0 protocol ip prio 1 root flower skip_sw \ action tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 id 555 \ dst_port 6635 tos 4 ttl 6 csum action mpls push protocol 0x8847 \ label 555 tc 3 action mirred egress redirect dev bareudp0 This is how the filter is shown with tc filter show: tc filter show dev enp59s0f0_0 ingress filter protocol ip pref 1 flower chain 0 filter protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 skip_sw in_hw in_hw_count 1 action order 1: tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.24 key_id 555 dst_port 6635 csum tos 0x4 ttl 6 pipe index 1 ref 1 bind 1 action order 2: mpls push protocol mpls_uc label 555 tc 3 ttl 255 pipe index 1 ref 1 bind 1 action order 3: mirred (Egress Redirect to device bareudp0) stolen index 1 ref 1 bind 1 Signed-off-by: Eli Cohen <eli@mellanox.com> Reviewed-by: Roi Dayan <roid@mellanox.com> Reviewed-by: Eli Britstein <elibr@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
