Hi @Balazs Nemeth
Please fix the following checkpatc.shh and check-git-log.sh issues and
add Igor reviewed by in next version.
I will merge the next version with the fixes. Updaed this series
status in the patchwork as "Changes requested"
Wrong headline format:
net/qede: remove flags from qede_tx_entry and simplify to rte_mbuf
net/qede: avoid repeatedly calling ecore_chain_get_cons_idx
net/qede: assume txq->sw_tx_ring[idx] is never null in qede_free_tx_pkt
net/qede: inline qede_free_tx_pkt to prepare for rte_pktmbuf_free_bulk
net/qede: use rte_pktmbuf_free_bulk instead of rte_pktmbuf_free
net/qede: prefetch txq->hw_cons_ptr
net/qede: remove page_offset from struct qede_rx_entry and simplify
Headline too long:
net/qede: remove flags from qede_tx_entry and simplify to rte_mbuf
net/qede: assume txq->sw_tx_ring[idx] is never null in qede_free_tx_pkt
net/qede: inline qede_free_tx_pkt to prepare for rte_pktmbuf_free_bulk
net/qede: use rte_pktmbuf_free_bulk instead of rte_pktmbuf_free
net/qede: remove page_offset from struct qede_rx_entry and simplify
