[PATCH net 3/4] ice: fix getting UDP tunnel entry

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Michal Swiatkowski <michal.swiatkowski@xxxxxxxxxxxxxxx>

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.

Fixes: b20e6c17c468 ("ice: convert to new udp_tunnel infrastructure")
