Hi Juhano
we do support RSS ESP out of the box on the SPI, src and dst IP fields
#define MLX5_HASH_IP_IPSEC_SPI (MLX5_HASH_FIELD_SEL_SRC_IP |\
MLX5_HASH_FIELD_SEL_DST_IP |\
MLX5_HASH_FIELD_SEL_IPSEC_SPI)
[MLX5E_TT_IPV4_IPSEC_ESP] = { .l3_prot_type = MLX5_L3_PROT_TYPE_IPV4,
.l4_prot_type = 0,
.rx_hash_fields =
MLX5_HASH_IP_IPSEC_SPI,
},
[MLX5E_TT_IPV6_IPSEC_ESP] = { .l3_prot_type = MLX5_L3_PROT_TYPE_IPV6,
.l4_prot_type = 0,
.rx_hash_fields =
MLX5_HASH_IP_IPSEC_SPI,
},
But we don't allow rss_hash_opt at the moment.
what exactly are you looking for ?
