2019-03-22net: Add IANA_VXLAN_UDP_PORT definition to vxlan header fileMoshe Shemesh5-8/+7
Added IANA_VXLAN_UDP_PORT (4789) definition to vxlan header file so it can be used by drivers instead of local definition. Updated drivers which locally defined it as 4789 to use it.

2019-03-22net/mlx5e: TX, Add geneve tunnel stateless offload supportMoshe Shemesh4-3/+77
Currently support only default geneve udp port (6081). For the tx side, the HW is assisted by SW parsing, which sets the headers offset to offload tunneled LSO and csum. Note that for udp tunnels, we don't use special rx offloads, as rss on the outer headers is enough, we support checksum complete and GRO takes care of aggregation. Geneve TSO BW and CPU load results (tested using iperf single tcp stream). In this patch we add TSO support over Geneve, so the "before" result doesn't actually get to using the TSO HW offload even when turned on. Tested on ConnectX-5, Intel(R) Xeon(R) CPU E5-2660 v2 @2.20GHz. __________________________________ | Before | After | |________________|_________________| | 12.6 Gbits/sec | 21.7 Gbits/sec | | 100% CPU load | 61.5% CPU load | |________________|_________________| Signed-off-by: Moshe Shemesh <[email protected]> Acked-by: Or Gerlitz <[email protected]> Signed-off-by: Saeed Mahameed <[email protected]>
2019-03-22net/mlx5e: Take SW parser code to a separate functionMoshe Shemesh2-24/+53
Refactor mlx5e_ipsec_set_swp() code, split the part which sets the eseg software parser (SWP) offsets and flags, so it can be used in a downstream patch by other mlx5e functionality which needs to set eseg SWP. The new function mlx5e_set_eseg_swp() is useful for setting swp for both outer and inner headers. It also handles the special ipsec case of xfrm mode transfer.

This patch fixes issue reclaiming VF resources back to the pool after reset - Since we only allocate HW vector for all VFs and track together with resources allocation for PF with ice_search_res, we need to free VFs resources separately, using first VF vector index to traverse the list. Otherwise tracker starts from the last assigned vectors list and causes maximum supported number of HW vectors, 1024 to be exhausted, depending on the number of VFs enabled, which causes a lot of unwanted issues, and failed to reassign vectors for VFs.

2019-03-22genetlink: make policy common to familyJohannes Berg5-29/+5
Since maxattr is common, the policy can't really differ sanely, so make it common as well. The only user that did in fact manage to make a non-common policy is taskstats, which has to be really careful about it (since it's still using a common maxattr!). This is no longer supported, but we can fake it using pre_doit. This reduces the size of e.g. nl80211.o (which has lots of commands): text data bss dec hex filename 398745 14323 2240 415308 6564c net/wireless/nl80211.o (before) 397913 14331 2240 414484 65314 net/wireless/nl80211.o (after) -------------------------------- -832 +8 0 -824 Which is obviously just 8 bytes for each command, and an added 8 bytes for the new policy pointer. I'm not sure why the ops list is counted as .text though. Most of the code transformations were done using the following spatch: @ops@ identifier OPS; expression POLICY; @@ struct genl_ops OPS[] = { ..., { - .policy = POLICY, }, ... }; @@ identifier ops.OPS; expression ops.POLICY; identifier fam; expression M; @@ struct genl_family fam = { .ops = OPS, .maxattr = M, + .policy = POLICY, ... }; This also gets rid of devlink_nl_cmd_region_read_dumpit() accessing the cb->data as ops, which we want to change in a later genl patch.
