[V4,01/10] net/bnxt: fix flow create failure
Checks
Commit Message
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
If flow create fails due to not enough filter resources,
driver does not populate the rte_flow_error using
rte_flow_error_set().
Since "rte_errno" could have garbage value and is not relaiable,
it could cause a segfault in the stack in port_flow_complain().
Fix it to set rte_flow_error using rte_flow_error_set()
when flow create fails due to not enough filter resources.
Fixes: 5c1171c ("net/bnxt: refactor filter/flow")
