This patch fixes possible memory leak inside the
ice_hash_parse_raw_pattern() due to the lack of a call to rte_free()
for previously allocated pkt_buf and msk_buf.

If the parser was not initialized when calling ice_hash_parse_raw_pattern()
-rte_errno was returned. Replace returning rte_errno with ENOTSUP since
rte_errno is meaningless in the context of ice_hash_parse_raw_pattern().

We are losing the error code retrn value here. I think the final return in
this function should be "return ret" rather than "return 0" so we can
propagate up the error.

Same here. Also the "if" statement before the "goto" is missing.

Are we not still missing an "if (ret != 0)" here?
If so, I can just add on apply.

Are we not still missing an "if (ret != 0)" here?
If so, I can just add on apply.
That's correct, will send v4

This patch fixes possible memory leak inside the
ice_hash_parse_raw_pattern() due to the lack of a call to rte_free()
for previously allocated pkt_buf and msk_buf.
Fixes: 1b9c68120a1c ("net/ice: enable protocol agnostic flow offloading in RSS")

If the parser was not initialized when calling ice_hash_parse_raw_pattern()
-rte_errno was returned. Replace returning rte_errno with ENOTSUP since
rte_errno is meaningless in the context of ice_hash_parse_raw_pattern().
