[dpdk-dev] [PATCH] net/iavf: fix performance drop after port reset

Needs to reset rxq->rxrearm_start to 0 when reset_rx_queue(), otherwise, the random value of rxrearm_start will cause performance drop due to L3 contested accesses. Fixes: 69dd4c3d0898 ("net/avf: enable queue and device") Signed-off-by: Leyi Rong --- drivers/net/iavf/iavf_rxtx.c | 1 + 1 file c
