[dpdk-dev] [PATCH] ixgbe: fix RX is not working properly when buffer address is not word aligned

> Niantic HW expects Header Buffer Address in the RXD to be word aligned.
> So, if mbuf's buf_physaddr is not word aligned then
> RX path will not work properly.
> Right now, in ixgbe PMD we always setup Packet Buffer Address(PBA) and
> Header Buffer Address (HBA) to the same value:
> buf_physaddr + RTE_PKTMBUF_HEADROOM.
> As ixgbe PMD doesn't support split header feature anyway,
> the issue can be fixied just by  always setting HBA in the RXD to zero.
