stable inclusion from stable-5.10.76 commit 69ea08c1b539657c0bea27d972f03b393caccc30 bugzilla: 182988 https://gitee.com/openeuler/kernel/issues/I4IAHF
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit e4c2efa1393c6f1fbfabf91d1d83fcb4ae691ccb ]
Correct parameters order in call to ice_tunnel_idx_to_entry function.
Entry in sparse port table is correct when the idx is 0. For idx 1 one correct entry should be skipped, for idx 2 two of them should be skipped etc. Change if condition to be true when idx is 0, which means that previous valid entry of this tunnel type were skipped.
