2020-01-27mlx5: Use dev_net netdevice notifier registrationsJiri Pirko1-0/+1
Register the dev_net notifier and allow the per-net notifier to follow the device into different namespace. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-01-06net/mlx5e: Fix hairpin RSS table sizeEli Cohen1-0/+16
Set hairpin table size to the corret size, based on the groups that would be created in it. Groups are laid out on the table such that a group occupies a range of entries in the table. This implies that the group ranges should have correspondence to the table they are laid upon. The patch cited below made group 1's size to grow hence causing overflow of group range laid on the table.

2019-08-28net/mlx5e: Support RSS for IP-in-IP and IPv6 tunneled packetsAya Levin1-0/+4
Add support for inner header RSS on IP-in-IP and IPv6 tunneled packets. Add rules to the steering table regarding outer IP header, with IPv4/6->IP-in-IP. Tunneled packets with protocol numbers: 0x4 (IP-in-IP) and 0x29 (IPv6) are RSS-ed on the inner IP header. Separate FW dependencies between flow table inner IP capabilities and GRE offload support. Allowing this feature even if GRE offload is not supported. Tested with multi stream TCP traffic tunneled with IPnIP. Verified that: Without this patch, only a single RX ring was processing the traffic. With this patch, multiple RX rings were processing the traffic. Verified with and without GRE offload support.

Move function which indicates whether tunnel inner flow table is supported from en.h to en_fs.c. It fits better right after tunnel protocol rules definitions.

2019-08-09net/mlx5e: Extend mod header entry with reference counterVlad Buslov1-1/+1
List of flows attached to mod header entry is used as implicit reference counter (mod header entry is deallocated when list becomes free) and as a mechanism to obtain mod header entry that flow is attached to (through list head). This is not safe when concurrent modification of list of flows attached to mod header entry is possible. Proper atomic reference counter is required to support concurrent access. As a preparation for extending mod header with reference counting, extract code that lookups and deletes mod header entry into standalone put/get helpers. In order to remove this dependency on external locking, extend mod header entry with reference counter to manage its lifetime and extend flow structure with direct pointer to mod header entry that flow is attached to. To remove code duplication between legacy and switchdev mode implementations that both support mod_hdr functionality, store mod_hdr table in dedicated structure used by both fdb and kernel namespaces. New table structure is extended with table lock by one of the following patches in this series. Implement helper function to get correct mod_hdr table depending on flow namespace.

2019-07-29net/mlx5e: Protect tc flow table with mutexVlad Buslov1-0/+2
TC flow table is created when first flow is added, and destroyed when last flow is removed. This assumes that all accesses to the table are externally synchronized with rtnl lock. To remove dependency on rtnl lock, add new mutex mlx5e_tc_table->t_lock and use it to protect the flow table.

Don't choose who implements the rxnfc "get/set" callbacks according to CONFIG_MLX5_EN_RXNFC, instead have the callbacks always available and delegate to a function of a different driver module when needed (en_fs_ethtool.c), have stubs in en/fs.h to fallback to when en_fs_ethtool.c is compiled out, to avoid complications and ifdefs in en_main.c.

2018-12-05net/mlx5e: Refactor TIR configuration functionAya Levin1-0/+16
Refactor mlx5e_build_indir_tir_ctx_hash for better code re-use. TIR stands for Transport Interface Receive, which is responsible for all transport related operations on the receive side. Added a static array with TIR default configuration values. This separates configuration values from command setting, which is needed for downstream patch.
