Bug ID: 1145
Summary: net/ice fdir flow create/destroy failed with
RTE_LIBRTE_ICE_16BYTE_RX_DESC defined
Product: DPDK
Version: 21.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: major
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: hanshuan...@gmail.com
Target Milestone: ---
Fdir rx queue use the same ice_rx_queue struct as packet rx queue.
When RTE_LIBRTE_ICE_16BYTE_RX_DESC defined rxq->rx_ring type is
ice_16b_rx_flex_desc.
#ifdef RTE_LIBRTE_ICE_16BYTE_RX_DESC
#define ice_rx_flex_desc ice_16b_rx_flex_desc
#else
#define ice_rx_flex_desc ice_32b_rx_flex_desc
#endif
But ice_check_fdir_programming_status check the rxdp assuming that rx_ring type
is ice_32byte_rx_desc.
rxdp = (volatile union ice_32byte_rx_desc *)(&rxq->rx_ring[rxq->rx_tail]);
I think this patch will fix the bug, but not the best solution：
