The build failure is legitimate here since 
drivers/net/ethernet/mellanox/mlx5/core/en_accel/ipsec.h guards all of 
the definitions and enumerations under a CONFIG_MLX5_EN_IPSEC which is 
not enabled in the build configuration that failed.

This is implicitly fixed upstream with 
8c582ddfbb473c1d799c40b5140aed81278e2837 ("net/mlx5e: Handle hardware 
IPsec limits events") which relocates the #ifdef CONFIG_MLX5_EN_IPSEC 
below and allows the MLX5_IPSEC_CAP_CRYPTO enum value, amongst others to 
be visible to code that is not guarded with CONFIG_MLX5_EN_IPSEC. This 
specific commit does not apply cleanly to the stable-6.1 branch, so 
maybe the best we can come up with is this targeted change that does the 
same thing against 6.1:
