Subject: nfp: flower: enabled offloading of Team LAG
Patch-mainline: v4.19-rc1
Git-commit: 635cf43dbddd166cd702c7883c837b9a3ace4565
References: bsc#1109837

Currently the NFP fw only supports L3/L4 hashing so rejects the offload of
filters that output to LAG ports implementing other hash algorithms. Team,
however, uses a BPF function for the hash that is not defined. To support
Team offload, accept hashes that are defined as 'unknown' (only Team
defines such hash types). In this case, use the NFP default of L3/L4
hashing for egress port selection.
