Subject: Re: [dpdk-dev] [PATCH] net/bnx2x: reserve enough headroom for mbuf prepend
When allocating a new mbuf for Rx, the value of m->data_off should be
reset to its default value (RTE_PKTMBUF_HEADROOM), instead of reusing
the previous undefined value, which could cause the packet to have a too
small or too high headroom.

When allocating a new mbuf for Rx, the value of m->data_off should be
reset to its default value (RTE_PKTMBUF_HEADROOM), instead of reusing
the previous undefined value, which could cause the packet to have a too
small or too high headroom.

Hi Yangchao,
There are multiple version of this patch and all seems marked as rejected in
patchwork, intentionally?
If not can you please update the correct one as new in patchwork?
