In Spectrum-1, RIFs representing ip6gre tunnels require two entries + in the RIF table. + +2. In Spectrum-2 and newer ASICs, packets ingress the underlay (during + encapsulation) and egress the underlay (during decapsulation) via a + special generic loopback RIF. + +The first difference was handled in previous patches by adding the +'double_rif_entry' field to the Spectrum-1 operations structure of +ip6gre RIFs. The second difference is handled during RIF creation, by +only creating a generic loopback RIF in Spectrum-2 and newer ASICs. + +Therefore, the ip6gre operations can be shared between Spectrum-1 and +newer ASIC in a similar fashion to how the ipgre operations are shared. + +Rename the operations to not be Spectrum-2 specific and move them +earlier in the file so that they could later be used for Spectrum-1. + +Signed-off-by: Ido Schimmel +Reviewed-by: Amit Cohen +Signed-off-by: Petr Machata +Signed-off-by: Jakub Kicinski +Stable-dep-of: 12ae97c531fc ("mlxsw: spectrum_ipip: Fix memory leak when changing remote IPv6 address") +Signed-off-by: Sasha Levin +--- + .../ethernet/mellanox/mlxsw/spectrum_ipip.c | 94 +++++++++---------- + 1 file changed, 47 insertions(+), 47 deletions(-) + +diff --git a/drivers/net/ethernet/mellanox/mlxsw/spectrum_ipip.c b/drivers/net/ethernet/mellanox/mlxsw/spectrum_ipip.c +index 7ed4b64fecc7a..fd421fbfc71bd 100644 +--- a/drivers/net/ethernet/mellanox/mlxsw/spectrum_ipip.c ++++ b/drivers/net/ethernet/mellanox/mlxsw/spectrum_ipip.c +@@ -429,28 +429,8 @@ mlxsw_sp1_ipip_rem_addr_unset_gre6(struct mlxsw_sp *mlxsw_sp, + WARN_ON_ONCE(1);
