[dpdk-dev] [PATCH 5/9] net/bnxt: set flow error when tunnel redirection free fails

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

During flow destroy, when bnxt_hwrm_tunnel_redirect_free() fails,
driver is not setting flow error using "rte_flow_error_set".

Fixes: 11e5e19695c7 ("net/bnxt: support redirecting tunnel packets to VF")
